Detailed Description

An ARTexture is a class representing a 2D texture. Textures cannot exceed 2048x2048 pixels in size.

Method Documentation

- (void) generateTexture

Generates texture names using texure id.

- (instancetype) initWithEmpty

Create an empty texture to be loaded with an image later.

Example of use:

ARTexture *texture = [[ARTexture alloc] initWithEmpty];

- (instancetype) initWithUIImage:

(UIImage *)

image

Create a texture from a UIImage.

Example of use:

ARTexture *texture = [[ARTexture alloc] initWithUIImage:[UIImage imageNamed:@"example.jpg"]];

Parameters

image

The UIImage to create the texture from.

- (void) loadTextureFromUIImage:		(UIImage *)	image
reverseLines:		(BOOL)	reverseLines

Loads image data into rawimage, sets image width and height, sets pixel format.

Parameters

image	Image to generate texture from.
reverseLines	Whether to read pixels from top(YES) or bottom.

- (void) postRender

Method called just after this texture has been used in rendering.

- (BOOL) preRender

Method called just before this texture is rendered.

Returns

BOOL Whether or not to proceed with rendering.

- (void) uploadTexture

Uploads texture to OpenGL.

Property Documentation

- (unsigned long) height

readwritenonatomicassign

The height of the texture, in pixels.

- (ARTextureFilter) magnificationFilter

readwritenonatomicassign

The filtering type used for magnification. ARTextureFilterLinear is recommended for less aliasing.

- (ARTextureFilter) minificationFilter

readwritenonatomicassign

The filtering type used for minification. ARTextureFilterLinear is recommended for less aliasing.

- (unsigned) textureID

readwritenonatomicassign

Texture name in OpenGL.

- (unsigned long) width

readwritenonatomicassign

The width of the texture, in pixels.
