Member Function Documentation

applyMaterialUniforms()

void copakond::Shader::applyMaterialUniforms

(

std::shared_ptr< Material >

mat

)

Binds material properties and active textures to the shader pipeline.

draw()

void copakond::Shader::draw	(	Mesh &	mesh,
		bool	drawTransparent,
		float	deltaTime )

Issues draw calls for a specific mesh.

Parameters

drawTransparent	If true, renders only transparent submeshes (for blending). If false, renders opaque.
deltaTime	Passed for procedural vertex wave animations.

getWorldAmbient()

glm::vec3 copakond::Shader::getWorldAmbient ( )

inlinestatic

init()

GLuint copakond::Shader::init	(	std::string	vertShaderLocation,
		std::string	fragShaderLocation )

Compiles and links vertex and fragment shaders.

Returns

The generated OpenGL shader program ID.

setLight()

void copakond::Shader::setLight	(	Light *	light,
		int	lightIndex )

update()

void copakond::Shader::update	(	Camera &	camera,
		int	winWidth,
		int	winHeight,
		float	deltaTime )

Updates global shader uniforms (Camera, Fog, Time).

updateLight()
