inline

Compile and link a 3D shader program.

Parameters

programOptions	base options for the ShaderProgram, see ShaderProgramOptions.
options	additional options for the shader, see Shader3DOptions.

Exceptions

graphics::Error	on failure to create a shader object, create the shader program object, compile the shader code or link the shader program.
std::bad_alloc	on allocation failure.

Member Data Documentation

VERTEX_SHADER_SOURCE_CODE_INSTANCED_MODEL

const char* const donut::graphics::Shader3D::VERTEX_SHADER_SOURCE_CODE_INSTANCED_MODEL

static

Pointer to a statically allocated string containing the GLSL source code for a plain vertex shader.

Examples

example_game.cpp.

FRAGMENT_SHADER_SOURCE_CODE_UNLIT

const char* const donut::graphics::Shader3D::FRAGMENT_SHADER_SOURCE_CODE_UNLIT

static

Pointer to a statically allocated string containing the GLSL source code for a fragment shader that uses a fullbright shading model with no lights.

Note

This shader uses only the diffuse texture and renders it at 100% brightness without taking details such as specular highlights, normal mapping or emissive color into account.

FRAGMENT_SHADER_SOURCE_CODE_BLINN_PHONG

const char* const donut::graphics::Shader3D::FRAGMENT_SHADER_SOURCE_CODE_BLINN_PHONG

static

Pointer to a statically allocated string containing the GLSL source code for a fragment shader that uses the Blinn-Phong shading model with a single basic point light at a fixed position.

Note

This basic shader should mainly be used for testing or debugging since the light parameters are completely arbitrary. Proper 3D applications should typically use a custom fragment shader that receives the light positions and colors as uniform data instead.

UNLIT

Shader3D* const donut::graphics::Shader3D::UNLIT

static

Pointer to the statically allocated storage for the built-in unlit shader.

Warning

This pointer must not be dereferenced in application code. It is not guaranteed that the underlying shader will be present at all times.

BLINN_PHONG

Shader3D* const donut::graphics::Shader3D::BLINN_PHONG

static

Pointer to the statically allocated storage for the built-in blinn-phong shader.

Warning

This pointer must not be dereferenced in application code. It is not guaranteed that the underlying shader will be present at all times.
