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

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

◆ bindToShaderProgram()

void CSCI441::UniformBufferObject::bindToShaderProgram ( ShaderProgram * shaderProgram )

inline

sets the shader programs binding point to match this uniform buffer object

Parameters

shaderProgram

Note: need to call UniformBufferObject::setupWithShaderProgram() before calling this with a second shader program

◆ copyToBuffer()

void CSCI441::UniformBufferObject::copyToBuffer	(	const char *	UNIFORM_NAME,
		const void *	src,
		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
src	starting address of source to copy from
len	length of buffer to copy

◆ copyToOffset()

void CSCI441::UniformBufferObject::copyToOffset	(	unsigned int	offset,
		const void *	src,
		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
src	starting address of source to copy from
len	length of buffer to copy

◆ operator=() [1/2]

CSCI441::UniformBufferObject & CSCI441::UniformBufferObject::operator= ( UniformBufferObject && src )

inlinenoexcept

Move Assign an existing UBO.

Returns: this now reconfigured UBO

◆ operator=() [2/2]

UniformBufferObject & CSCI441::UniformBufferObject::operator= ( UniformBufferObject & unused )

delete

Note: cannot copy UBOs
