Class GLTextureWow

java.lang.Object
  hmi.environment.GLTextureWow

public class GLTextureWow
extends Object

2D texture. For non power of two images there are three options: hardware, stretch, and pad. For pad, non power of two images are mapped to the bottom left corner of a power of two texture. Use getMaxS() and getMaxT() to get the float coordinates of the topright corner (bottom left corner is 0,0). For stretch, non power of two images are stretched to fit the power of two texture. user getSStretch() and getTStretch() to get the stretch factors. Supported (set through mipmaps and smooth flags): GL_TEXTURE_MIN_FILTER, GL_TEXTURE_MAG_FILTER, GL_TEXTURE_MIN_LOD, GL_TEXTURE_MAX_LOD, GL_TEXTURE_BASE_LEVEL, GL_TEXTURE_MAX_LEVEL, Set through wrap: GL_TEXTURE_WRAP_S, GL_TEXTURE_WRAP_T N/A: GL_TEXTURE_WRAP_R not supported: GL_TEXTURE_PRIORITY
