Public Member Functions | |
| GLuint | getTextureId () const |
| Read-only access to the stored texture ID's. This function will NOT create any texture ID's. | |
| GLTextureID (type TextureTarget, int TextureUnit) throw () | |
| Constructor, specify texture unit. | |
| bool | isValid () const |
| Check whether a valid texture ID is stored here. | |
| GLuint | makeTextureId () |
| On first access, OpenGL textures will be generated. | |
| operator bool () const | |
| Check whether a valid texture ID is stored here. | |
| bool | selectActiveTextureUnit () const |
| ~GLTextureID () | |
| Deletion of created OpenGL textures. Note that this destructor crashes if called outside a valid OpenGL context. | |
Public Attributes | |
| const type | target |
| The corresponding OpenGL texture target (GL_TEXTURE_nD) | |
Detailed Description
Better base class for OpenGL Texture ID's.
Supports multiple active texture units as specified in OpenGL 2.
Member Function Documentation
◆ makeTextureId()
| GLuint Wizt::GLTextureID::makeTextureId | ( | ) |
On first access, OpenGL textures will be generated.
This function must be called from within a valid OpenGL context.
◆ selectActiveTextureUnit()
| bool Wizt::GLTextureID::selectActiveTextureUnit | ( | ) | const |
- Returns
- false if active texture are not supported, such as in ancient OpenGL
