Description

Cross-Compiles GLSL vertex and fragment shader code to SPIR-V and creates a Vulkan shader module. All uniforms, samplers and attributes are extracted. Make sure to call init() on initialization of a derived shader class. A nap::Material links to a BaseShader. The shader is compiled on initialization. Use a nap::ComputeMaterial or nap::ComputeMaterialInstance to set / override uniforms and samplers.

Member Function Documentation

◆ getComputeModule()

VkShaderModule getComputeModule ( ) const
Returns
Vulkan vertex module.

◆ getWorkGroupSize()

const glm::uvec3& getWorkGroupSize ( ) const
Returns
local work group size

◆ getWorkGroupSizeOverrides()

const std::unordered_map<uint, std::string>& getWorkGroupSizeOverrides ( ) const

Map of specialization constant names that are available to override a workgroup dimension size. Key : dimension[0, 1, 2], Value: constant_name

Returns
workgroup dimension to override specialization constant name

◆ load()

virtual bool load ( const std::string &  displayName,
const std::vector< std::string > &  searchPaths,
const char *  compShader,
int  compSize,
utility::ErrorState errorState 
)
protectedvirtual

Compiles the GLSL shader code, creates the shader module and parses all the uniforms and samplers. Call this in a derived class on initialization.

Parameters
displayNamethe name of the shader
searchPathsthe search paths of the shader.
compShaderthe fragment shader GLSL code.
compSizetotal number of characters in compShader.
errorStatecontains the error if initialization fails.
Returns
if initialization succeeded.
