Helper function for loading an image file from disk, converting it to DDS, and storing it in the specified char vector property.

Parameters

node	handle to the node to set the property on
propName	name of the property
file	path to the file to read, if not found, an error pattern is set instead
compress	whether to compress the texture using DXT1

Returns: 0 if property is successfully populated with data from the file in DDS format

uint32_t VRGetTextureFormat(

textureNode

)

Helper function for getting the OpenGL texture format out of a texture node.

Parameters

textureNode	handle to the texture node

Returns: 0 if node has no DDSData property, otherwise the GLenum value representing the texture format

TextureInfo VRGetTextureInfo(

textureNode

)

Helper function for getting the OpenGL texture information out of a texture node.

Parameters

textureNode	handle to the texture node

Returns: information reguarding texture paramaters, values will be 0 on faliure
