Detailed Description

A simple wrapper around an OpenGL Texture

Definition at line 90 of file al_Texture.hpp.

Member Function Documentation

◆ bind()

void al::Texture::bind ( int binding_point = 0 )

Bind the texture (to a multitexture unit) also update params and mipmap if changed

◆ bind_temp()

void al::Texture::bind_temp ( )

use last binding point so it doesn't collide with user's binding also bind without updating params

◆ copyFrameBuffer()

void al::Texture::copyFrameBuffer	(	int	w = `-1`,
		int	h = `-1`,
		int	fbx = `0`,
		int	fby = `0`,
		int	texx = `0`,
		int	texy = `0`,
		int	texz = `0`
	)

Copy pixels from current frame buffer to texture texels.

Parameters

[in]	w	width of region to copy; w<0 uses w + 1 + texture.width
[in]	h	height of region to copy; h<0 uses h + 1 + texture.height
[in]	fbx	pixel offset from left edge of frame buffer
[in]	fby	pixel offset from bottom edge of frame buffer
[in]	texx	texel offset in x direction
[in]	texy	texel offset in y direction (2D/3D only)
[in]	texz	texel offset in z direction (3D only)

◆ resize()

void al::Texture::resize ( unsigned w )

inline

Get number of components per pixel.

Get total number of elements (components x width x height x depth) Get total number of pixels Resize 1D texture

Definition at line 263 of file al_Texture.hpp.

◆ submit()

void al::Texture::submit	(	const void *	pixels,
		unsigned int	format,
		unsigned int	type
	)

Copy client pixels to GPU texels NOTE: the graphics context (e.g. Window) must have been created If pixels is NULL, then the only effect is to resize the texture remotely.

◆ validate()

void al::GPUObject::validate ( )

inherited

Ensure that the GPUObject is ready to use.

This is typically placed before any rendering implementation. If the object has been invalidated, the object will be destroyed and then created again. Otherwise, the object will simply be created if not already created.

The documentation for this class was generated from the following file:
