Public Member Functions | |
OpenGl_Texture (const Handle< Graphic3d_TextureParams > &theParams=NULL) | |
Create uninitialized VBO. | |
virtual | ~OpenGl_Texture () |
Destroy object. | |
bool | IsValid () const |
GLenum | GetTarget () const |
GLsizei | SizeX () const |
GLsizei | SizeY () const |
GLuint | TextureId () const |
bool | Create (const Handle< OpenGl_Context > &theCtx) |
Creates Texture id if not yet generated. Data should be initialized by another method. | |
virtual void | Release (const OpenGl_Context *theCtx) |
Destroy object - will release GPU memory if any. | |
void | Bind (const Handle< OpenGl_Context > &theCtx, const GLenum theTextureUnit=GL_TEXTURE0) const |
Bind this Texture to specified unit. | |
void | Unbind (const Handle< OpenGl_Context > &theCtx, const GLenum theTextureUnit=GL_TEXTURE0) const |
Unbind texture from specified unit. | |
bool | Init (const Handle< OpenGl_Context > &theCtx, const Image_PixMap &theImage, const Graphic3d_TypeOfTexture theType) |
Notice that texture will be unbound after this call. | |
