Member Enumeration Documentation

enum GrShaderCaps::AdvBlendEqInteraction

Indicates how GLSL must interact with advanced blend equations.

The KHR extension requires special layout qualifiers in the fragment shader.

Member Function Documentation

const GrSwizzle& GrShaderCaps::configOutputSwizzle ( GrPixelConfig config ) const

inline

Swizzle that should occur on the fragment shader outputs for a given config.

const GrSwizzle& GrShaderCaps::configTextureSwizzle ( GrPixelConfig config ) const

inline

Given a texture's config, this determines what swizzle must be appended to accesses to the texture in generated shader code.

Swizzling may be implemented in texture parameters or a sampler rather than in the shader. In this case the returned swizzle will always be "rgba".

bool GrShaderCaps::fbFetchSupport ( ) const

inline

Some helper functions for encapsulating various extensions to read FB Buffer on openglES.

TODO(joshualitt) On desktop opengl 4.2+ we can achieve something similar to this effect

const PrecisionInfo& GrShaderCaps::getFloatShaderPrecisionInfo	(	GrShaderType	shaderType,
		GrSLPrecision	precision
	)		const

inline

Get the precision info for a variable of type kFloat_GrSLType, kVec2f_GrSLType, etc in a given shader type.

If the shader type is not supported or the precision level is not supported in that shader type then the returned struct will report false when supported() is called.

void GrShaderCaps::initSamplerPrecisionTable ( )

private

GrCaps subclasses must call this after filling in the shader precision table.

GrSLPrecision GrShaderCaps::samplerPrecision	(	GrPixelConfig	config,
		GrShaderFlags	visibility
	)		const

inline

Precision qualifier that should be used with a sampler, given its config and visibility.
