vk2dShaderFree()

void vk2dShaderFree

(

VK2DShader

shader

)

Frees a shader from memory.

Parameters

shader

Shader to free

vk2dShaderFrom()

VK2DShader vk2dShaderFrom	(	uint8_t *	vertexShaderBuffer,
		int	vertexShaderBufferSize,
		uint8_t *	fragmentShaderBuffer,
		int	fragmentShaderBufferSize,
		uint32_t	uniformBufferSize
	)

Creates a shader you can use to render textures from an in-memory buffer.

Parameters

vertexShaderBuffer	Buffer containing compiled SPIR-V shader code
vertexShaderBufferSize	Size of the vertexShaderBuffer buffer in bytes
fragmentShaderBuffer	File containing the compiled SPIR-V fragment shader
fragmentShaderBufferSize	Size of the fragmentShaderBuffer buffer in bytes
uniformBufferSize	Size of the shader's expected uniform buffer (0 is valid)

Returns

Returns a new shader or NULL

Warning

There are strict requirements for how the shader should be constructed

uniformBufferSize must be less than the maxShaderBufferSize field of vk2dRendererGetLimits

uniformBufferSize must be a multiple of 4

Check the shaders shaders/tex.vert and shaders/tex.frag for information on how the shaders should be set up. You may choose to not include a uniform buffer if you specify a uniform buffer size of 0.

vk2dShaderLoad()

VK2DShader vk2dShaderLoad	(	const char *	vertexShader,
		const char *	fragmentShader,
		uint32_t	uniformBufferSize
	)

Creates a shader you can use to render textures.

Parameters

vertexShader	File containing the compiled SPIR-V vertex shader
fragmentShader	File containing the compiled SPIR-V fragment shader
uniformBufferSize	Size of the shader's expected uniform buffer (0 is valid)

Returns

Returns a new shader or NULL
