They may change from version to version. - * - * The shader has three passes, chained together as follows: - * - * |input|------------------? - * v | - * [ SMAA*EdgeDetection ] | - * v | - * |edgesTex| | - * v | - * [ SMAABlendingWeightCalculation ] | - * v | - * |blendTex| | - * v | - * [ SMAANeighborhoodBlending ] <------? - * v - * |output| - * - * Note that each [pass] has its own vertex and pixel shader. Remember to use - * oversized triangles instead of quads to avoid overshading along the - * diagonal. - * - * You've three edge detection methods to choose from: luma, color or depth. - * They represent different quality/performance and anti-aliasing/sharpness - * tradeoffs, so our recommendation is for you to choose the one that best - * suits your particular scenario: - * - * - Depth edge detection is usually the fastest but it may miss some edges. - * - * - Luma edge detection is usually more expensive than depth edge detection, - * but catches visible edges that depth edge detection can miss. - * - * - Color edge detection is usually the most expensive one but catches - * chroma-only edges. - * - * For quickstarters: just use luma edge detection. - * - * The general advice is to not rush the integration process and ensure each - * step is done correctly (don't try to integrate SMAA T2x with predicated edge - * detection from the start!). Ok then, let's go! - * - * 1. The first step is to create two RGBA temporal render targets for holding - * |edgesTex| and |blendTex|. - * - * In DX10 or DX11, you can use a RG render target for the edges texture. - * In the case of NVIDIA GPUs, using RG render targets seems to actually be - * slower. - * - * On the Xbox 360, you can use the same render target for resolving both - * |edgesTex| and |blendTex|, as they aren't needed simultaneously. - * - * 2. Both temporal render targets |edgesTex| and |blendTex| must be cleared - * each frame. Do not forget to clear the alpha channel! - * - * 3. The next step is loading the two supporting precalculated textures, - * 'areaTex' and 'searchTex'. You'll find them in the 'Textures' folder as - * C++ headers, and also as regular DDS files. They'll be needed for the - * 'SMAABlendingWeightCalculation' pass. - * - * If you use the C++ headers, be sure to load them in the format specified - * inside of them. - * - * You can also compress 'areaTex' and 'searchTex' using BC5 and BC4 - * respectively, if you have that option in your content processor pipeline. - * When compressing then, you get a non-perceptible quality decrease, and a - * marginal performance increase. - * - * 4. All samplers must be set to linear filtering and clamp. - * - * After you get the technique working, remember that 64-bit inputs have - * half-rate linear filtering on GCN. - * - * If SMAA is applied to 64-bit color buffers, switching to point filtering - * when accesing them will increase the performance. Search for - * 'SMAASamplePoint' to see which textures may benefit from point - * filtering, and where (which is basically the color input in the edge - * detection and resolve passes). - * - * 5. All texture reads and buffer writes must be non-sRGB, with the exception - * of the input read and the output write in - * 'SMAANeighborhoodBlending' (and only in this pass!). If sRGB reads in - * this last pass are not possible, the technique will work anyway, but - * will perform antialiasing in gamma space. - * - * IMPORTANT: for best results the input read for the color/luma edge - * detection should *NOT* be sRGB. - * - * 6. Before including SMAA.h you'll have to setup the render target metrics, - * the target and any optional configuration defines. Optionally you can - * use a preset. - * - * You have the following targets available: - * SMAA_HLSL_3 - * SMAA_HLSL_4 - * SMAA_HLSL_4_1 - * SMAA_GLSL_3 * - * SMAA_GLSL_4 * - * - * * (See SMAA_INCLUDE_VS and SMAA_INCLUDE_PS below). - * - * And four presets: - * SMAA_PRESET_LOW (%60 of the quality) - * SMAA_PRESET_MEDIUM (%80 of the quality) - * SMAA_PRESET_HIGH (%95 of the quality) - * SMAA_PRESET_ULTRA (%99 of the quality) - * - * For example: - * #define SMAA_RT_METRICS vec4(1.0 / 1280.0, 1.0 / 720.0, 1280.0, 720.0) - * #define SMAA_GLSL_4 - * #define SMAA_PRESET_HIGH - * #include "SMAA.h" - * - * Note that SMAA_RT_METRICS doesn't need to be a macro, it can be a - * uniform variable. The code is designed to minimize the impact of not - * using a constant value, but it is still better to hardcode it. - * - * Depending on how you encoded 'areaTex' and 'searchTex', you may have to - * add (and customize) the following defines before including SMAA.h: - * #define SMAA_AREATEX_SELECT(sample) sample.rg - * #define SMAA_SEARCHTEX_SELECT(sample) sample.r - * - * If your engine is already using porting macros, you can define - * SMAA_CUSTOM_SL, and define the porting functions by yourself. - * - * 7. Then, you'll have to setup the passes as indicated in the scheme above. - * You can take a look into SMAA.fx, to see how we did it for our demo. - * Checkout the function wrappers, you may want to copy-paste them! - * - * 8. It's recommended to validate the produced |edgesTex| and |blendTex|. - * You can use a screenshot from your engine to compare the |edgesTex| - * and |blendTex| produced inside of the engine with the results obtained - * with the reference demo. - * - * 9. After you get the last pass to work, it's time to optimize. You'll have - * to initialize a stencil buffer in the first pass (discard is already in - * the code), then mask execution by using it the second pass. The last - * pass should be executed in all pixels. - * - * - * After this point you can choose to enable predicated thresholding, - * temporal supersampling and motion blur integration: - * - * a) If you want to use predicated thresholding, take a look into - * SMAA_PREDICATION; you'll need to pass an extra texture in the edge - * detection pass. - * - * b) If you want to enable temporal supersampling (SMAA T2x): - * - * 1. The first step is to render using subpixel jitters. I won't go into - * detail, but it's as simple as moving each vertex position in the - * vertex shader, you can check how we do it in our DX10 demo. - * - * 2. Then, you must setup the temporal resolve. You may want to take a look - * into SMAAResolve for resolving 2x modes. After you get it working, you'll - * probably see ghosting everywhere. But fear not, you can enable the - * CryENGINE temporal reprojection by setting the SMAA_REPROJECTION macro. - * Check out SMAA_DECODE_VELOCITY if your velocity buffer is encoded. - * - * 3. The next step is to apply SMAA to each subpixel jittered frame, just as - * done for 1x. - * - * 4. At this point you should already have something usable, but for best - * results the proper area textures must be set depending on current jitter. - * For this, the parameter 'subsampleIndices' of - * 'SMAABlendingWeightCalculationPS' must be set as follows, for our T2x - * mode: - * - * @SUBSAMPLE_INDICES - * - * | S# | Camera Jitter | subsampleIndices | - * +----+------------------+---------------------+ - * | 0 | ( 0.25, -0.25) | float4(1, 1, 1, 0) | - * | 1 | (-0.25, 0.25) | float4(2, 2, 2, 0) | - * - * These jitter positions assume a bottom-to-top y axis. S# stands for the - * sample number. - * - * More information about temporal supersampling here: - * http://iryoku.com/aacourse/downloads/13-Anti-Aliasing-Methods-in-CryENGINE-3.pdf - * - * c) If you want to enable spatial multisampling (SMAA S2x): - * - * 1. The scene must be rendered using MSAA 2x. The MSAA 2x buffer must be - * created with: - * - DX10: see below (*) - * - DX10.1: D3D10_STANDARD_MULTISAMPLE_PATTERN or - * - DX11: D3D11_STANDARD_MULTISAMPLE_PATTERN - * - * This allows to ensure that the subsample order matches the table in - * @SUBSAMPLE_INDICES. - * - * (*) In the case of DX10, we refer the reader to: - * - SMAA::detectMSAAOrder and - * - SMAA::msaaReorder - * - * These functions allow to match the standard multisample patterns by - * detecting the subsample order for a specific GPU, and reordering - * them appropriately. - * - * 2. A shader must be run to output each subsample into a separate buffer - * (DX10 is required). You can use SMAASeparate for this purpose, or just do - * it in an existing pass (for example, in the tone mapping pass, which has - * the advantage of feeding tone mapped subsamples to SMAA, which will yield - * better results). - * - * 3. The full SMAA 1x pipeline must be run for each separated buffer, storing - * the results in the final buffer. The second run should alpha blend with - * the existing final buffer using a blending factor of 0.5. - * 'subsampleIndices' must be adjusted as in the SMAA T2x case (see point - * b). - * - * d) If you want to enable temporal supersampling on top of SMAA S2x - * (which actually is SMAA 4x): - * - * 1. SMAA 4x consists on temporally jittering SMAA S2x, so the first step is - * to calculate SMAA S2x for current frame. In this case, 'subsampleIndices' - * must be set as follows: - * - * | F# | S# | Camera Jitter | Net Jitter | subsampleIndices | - * +----+----+--------------------+-------------------+----------------------+ - * | 0 | 0 | ( 0.125, 0.125) | ( 0.375, -0.125) | float4(5, 3, 1, 3) | - * | 0 | 1 | ( 0.125, 0.125) | (-0.125, 0.375) | float4(4, 6, 2, 3) | - * +----+----+--------------------+-------------------+----------------------+ - * | 1 | 2 | (-0.125, -0.125) | ( 0.125, -0.375) | float4(3, 5, 1, 4) | - * | 1 | 3 | (-0.125, -0.125) | (-0.375, 0.125) | float4(6, 4, 2, 4) | - * - * These jitter positions assume a bottom-to-top y axis. F# stands for the - * frame number. S# stands for the sample number. - * - * 2. After calculating SMAA S2x for current frame (with the new subsample - * indices), previous frame must be reprojected as in SMAA T2x mode (see - * point b). - * - * e) If motion blur is used, you may want to do the edge detection pass - * together with motion blur. This has two advantages: - * - * 1. Pixels under heavy motion can be omitted from the edge detection process. - * For these pixels we can just store "no edge", as motion blur will take - * care of them. - * 2. The center pixel tap is reused. - * - * Note that in this case depth testing should be used instead of stenciling, - * as we have to write all the pixels in the motion blur pass. - * - * That's it! - */ - -//----------------------------------------------------------------------------- -// SMAA Presets - -/** - * Note that if you use one of these presets, the following configuration - * macros will be ignored if set in the "Configurable Defines" section. - */ - -#if defined(SMAA_PRESET_LOW) -#define SMAA_THRESHOLD 0.15 -#define SMAA_MAX_SEARCH_STEPS 4 -#define SMAA_DISABLE_DIAG_DETECTION -#define SMAA_DISABLE_CORNER_DETECTION -#elif defined(SMAA_PRESET_MEDIUM) -#define SMAA_THRESHOLD 0.1 -#define SMAA_MAX_SEARCH_STEPS 8 -#define SMAA_DISABLE_DIAG_DETECTION -#define SMAA_DISABLE_CORNER_DETECTION -#elif defined(SMAA_PRESET_HIGH) -#define SMAA_THRESHOLD 0.1 -#define SMAA_MAX_SEARCH_STEPS 16 -#define SMAA_MAX_SEARCH_STEPS_DIAG 8 -#define SMAA_CORNER_ROUNDING 25 -#elif defined(SMAA_PRESET_ULTRA) -#define SMAA_THRESHOLD 0.05 -#define SMAA_MAX_SEARCH_STEPS 32 -#define SMAA_MAX_SEARCH_STEPS_DIAG 16 -#define SMAA_CORNER_ROUNDING 25 -#endif - -//----------------------------------------------------------------------------- -// Configurable Defines - -/** - * SMAA_THRESHOLD specifies the threshold or sensitivity to edges. - * Lowering this value you will be able to detect more edges at the expense of - * performance. - * - * Range: [0, 0.5] - * 0.1 is a reasonable value, and allows to catch most visible edges. - * 0.05 is a rather overkill value, that allows to catch 'em all. - * - * If temporal supersampling is used, 0.2 could be a reasonable value, as low - * contrast edges are properly filtered by just 2x. - */ -#ifndef SMAA_THRESHOLD -#define SMAA_THRESHOLD 0.1 -#endif - -/** - * SMAA_DEPTH_THRESHOLD specifies the threshold for depth edge detection. - * - * Range: depends on the depth range of the scene. - */ -#ifndef SMAA_DEPTH_THRESHOLD -#define SMAA_DEPTH_THRESHOLD (0.1 * SMAA_THRESHOLD) -#endif - -/** - * SMAA_MAX_SEARCH_STEPS specifies the maximum steps performed in the - * horizontal/vertical pattern searches, at each side of the pixel. - * - * In number of pixels, it's actually the double.
