Constructor & Destructor Documentation

UniformBufferObject() [1/2]

CSCI441::UniformBufferObject::UniformBufferObject ( )

delete

Note

must use `UniformBufferObject(const char*, std::initializer_list<const char*>

UniformBufferObject() [2/2]

CSCI441::UniformBufferObject::UniformBufferObject ( const char *  UNIFORM_BLOCK_NAME, std::initializer_list< const char * >  uniformNamesList  )

inline

Initializes the UniformBufferObject object.

Parameters

UNIFORM_BLOCK_NAME	name of the uniform block
uniformNamesList	list of names that makeup the uniform block components

Member Function Documentation

copyToBuffer()

void CSCI441::UniformBufferObject::copyToBuffer ( const char *  UNIFORM_NAME, void *  addr, size_t  len  )

inline

copies the value pointed to by addr to the corresponding location within the UBO as denoted by the uniform name

Parameters

UNIFORM_NAME	name of the uniform within the block to copy value to
addr	starting address of source to copy from
len	length of buffer to copy

copyToOffset()

void CSCI441::UniformBufferObject::copyToOffset ( unsigned int  offset, void *  addr, size_t  len  )

inline

copies the value pointed to by addr to the corresponding location within the UBO as denoted by the offset

Parameters

offset	UBO offset to copy value to
addr	starting address of source to copy from
len	length of buffer to copy

setupWithShaderProgram()

void CSCI441::UniformBufferObject::setupWithShaderProgram ( ShaderProgram *  shaderProgram, GLuint  bindingPoint  )

inline

creates the UBO and allocates memory on both the CPU & GPU. binds the UBO and the uniform block for the provided ShaderProgram to the same binding point.

Parameters

shaderProgram	ShaderProgram object that utilizes the uniformBlock
bindingPoint	Binding point to bind the UBO and ShaderProgram Uniform Block to
