Detailed Description

Manages OpenGL shader program compilation and uniform setting.

Note

Automatically binds common uniform blocks (Camera, Lights, Rigidbody)

Warning

Shader sources must be valid GLSL code

Member Function Documentation

bindBlocks()

void solarsim::Shader::bindBlocks ( )

inline

Bind uniform buffer blocks to predefined binding points.

Note

Binds CameraBuffer(0), LightsBuffer(1), RigidbodyBuffer(2)

Warning

Call this after compilation, it's called automatically by compile()

checkCompileErrors()

void solarsim::Shader::checkCompileErrors ( uint32_t shader, const std::string & type )

inline

Check for shader compilation or linking errors.

Parameters

shader	Shader or program object to check
type	Type of shader ("VERTEX", "FRAGMENT", or "PROGRAM")

Note

Prints errors to std::cerr

compile()

void solarsim::Shader::compile ( const std::string & vertexSrc, const std::string & fragmentSrc )

inline

Compile and link shader program from source code.

Parameters

vertexSrc	Vertex shader source code
fragmentSrc	Fragment shader source code

Note

Automatically calls bindBlocks() after successful compilation

setUniform() [1/5]

void solarsim::Shader::setUniform ( const std::string & name, bool value )

inline

Set a boolean uniform value.

Parameters

name	Uniform variable name in shader
value	Boolean value (converted to 0 or 1)

setUniform() [2/5]

void solarsim::Shader::setUniform ( const std::string & name, const glm::mat4 & value )

inline

Set a mat4 uniform value.

Parameters

name	Uniform variable name in shader
value	4x4 matrix value

setUniform() [3/5]

void solarsim::Shader::setUniform ( const std::string & name, const glm::vec3 & value )

inline

Set a vec3 uniform value.

Parameters

name	Uniform variable name in shader
value	3-component vector value

setUniform() [4/5]

void solarsim::Shader::setUniform ( const std::string & name, float value )

inline

Set a float uniform value.

Parameters

name	Uniform variable name in shader
value	Single float value

setUniform() [5/5]

void solarsim::Shader::setUniform ( const std::string & name, int value )

inline

Set an integer uniform value.

Parameters

name	Uniform variable name in shader
value	Integer value

use()

void solarsim::Shader::use ( )

inline

Activate this shader for rendering.
