Detailed Description

Texture wrapper

Constructor & Destructor Documentation

Texture() [1/3]

oe::render::Texture::Texture	(	const std::string &	filename,
		const bool &	is_srgb = false,
		const uint8_t	max_mips = 1
	)

Load texture from a file

Parameters

filename	The image file
is_srgb	Set to true if the image need to be loaded as sRGB or linear color space

Note

You can omit the extension, this method will try the following extensions in order: .tga, .jpg, .png

Texture() [2/3]

oe::render::Texture::Texture	(	const uint32_t	width,
		const uint32_t	height,
		const std::function< glm::vec4(const uint32_t i, const uint32_t j)>	generator,
		const uint8_t	max_mips = 1
	)

Generate a RGBA texture from a function returning a vec4

Texture() [3/3]

oe::render::Texture::Texture	(	const uint32_t	width,
		const uint32_t	height,
		const oe::scene::Material &	generator,
		const int32_t	nb_channels = 0,
		const int32_t	internal_format = 0,
		const int32_t	format = 0,
		const int32_t	type = 0,
		const uint8_t	max_mips = 1
	)

Generate a texture from a material

Member Function Documentation

fetchTextureData()

std::vector< uint8_t > oe::render::Texture::fetchTextureData	(	const unsigned int &	face,
		const unsigned int &	mip_level
	)

Get texture data from OpenGL memory
