ó š3j" ãó`•SrSSKJrJrJr SSKJrJr SSKrSSKJ r J r SSK 7 SSK J r Sr g) a OpenGL extension EXT.shader_texture_lod This module customises the behaviour of the OpenGL.raw.GLES2.EXT.shader_texture_lod to provide a more Python-friendly API Overview (from the spec) This extension adds additional texture functions to the OpenGL ES Shading Language which provide the shader writer with explicit control of LOD. Mipmap texture fetches and anisotropic texture fetches require implicit derivatives to calculate rho, lambda and/or the line of anisotropy. These implicit derivatives will be undefined for texture fetches occurring inside non-uniform control flow or for vertex shader texture fetches, resulting in undefined texels. The additional texture functions introduced with this extension provide explicit control of LOD (isotropic texture functions) or provide explicit derivatives (anisotropic texture functions). Anisotropic texture functions return defined texels for mipmap texture fetches or anisotropic texture fetches, even inside non-uniform control flow. Isotropic texture functions return defined texels for mipmap texture fetches, even inside non-uniform control flow. However, isotropic texture functions return undefined texels for anisotropic texture fetches. The existing isotropic vertex texture functions: vec4 texture2DLodEXT(sampler2D sampler, vec2 coord, float lod); vec4 texture2DProjLodEXT(sampler2D sampler, vec3 coord, float lod); vec4 texture2DProjLodEXT(sampler2D sampler, vec4 coord, float lod); vec4 textureCubeLodEXT(samplerCube sampler, vec3 coord, float lod); are added to the built-in functions for fragment shaders with "EXT" suffix appended. New anisotropic texture functions, providing explicit derivatives: vec4 texture2DGradEXT(sampler2D sampler, vec2 P, vec2 dPdx, vec2 dPdy); vec4 texture2DProjGradEXT(sampler2D sampler, vec3 P, vec2 dPdx, vec2 dPdy); vec4 texture2DProjGradEXT(sampler2D sampler, vec4 P, vec2 dPdx, vec2 dPdy); vec4 textureCubeGradEXT(samplerCube sampler, vec3 P, vec3 dPdx, vec3 dPdy); are added to the built-in functions for vertex shaders and fragment shaders.
