Member Function Documentation

void Ogre::GLESTexture::_createGLTexResource ( )

protected

Create gl texture.

void Ogre::GLESTexture::_createSurfaceList ( )

protected

Internal method, create GLHardwarePixelBuffers for every face and mipmap level.

This method must be called after the GL texture object was created, the number of mipmaps was set (GL_TEXTURE_MAX_LEVEL) and glTexImageXD was called to actually allocate the buffer

void Ogre::GLESTexture::createInternalResourcesImpl ( void  )

protected

Implementation of creating internal texture resources.

void Ogre::GLESTexture::createRenderTexture

(

)

void Ogre::GLESTexture::freeInternalResourcesImpl ( void  )

protected

Implementation of freeing internal texture resources.

HardwarePixelBufferSharedPtr Ogre::GLESTexture::getBuffer	(	size_t	face,
		size_t	mipmap
	)

Return hardware pixel buffer for a surface.

This buffer can then be used to copy data from and to a particular level of the texture.

Parameters

face	Face number, in case of a cubemap texture. Must be 0 for other types of textures. For cubemaps, this is one of +X (0), -X (1), +Y (2), -Y (3), +Z (4), -Z (5)
mipmap	Mipmap level. This goes from 0 for the first, largest mipmap level to getNumMipmaps()-1 for the smallest.

Returns

A shared pointer to a hardware pixel buffer

Remarks

The buffer is invalidated when the resource is unloaded or destroyed. Do not use it after the lifetime of the containing texture.

void Ogre::GLESTexture::loadImpl ( void  )

protected

Internal implementation of the meat of the 'load' action, only called if this resource is not being loaded from a ManualResourceLoader.

virtual void Ogre::GLESTexture::notifyOnContextLost ( )

protectedvirtual

See AndroidResource.

virtual void Ogre::GLESTexture::notifyOnContextReset ( )

protectedvirtual

See AndroidResource.

void Ogre::GLESTexture::prepareImpl ( void  )

protected

Internal implementation of the meat of the 'prepare' action.

void Ogre::GLESTexture::unprepareImpl ( void  )

protected

Internal function for undoing the 'prepare' action.

Called when the load is completed, and when resources are unloaded when they are prepared but not yet loaded.

LoadedImages Ogre::GLESTexture::mLoadedImages

protected

Vector of images that were pulled from disk by prepareLoad but have yet to be pushed into texture memory by loadImpl.

Images should be deleted by loadImpl and unprepareImpl.
