| int glArrayElement (GLint i); | |
| void glBegin (void); |
No tests are performed to prevent some functions
of being executed between glBegin/glEnd. |
| void glBindTexture (GLenum target,
GLuint texture); |
|
| void glBlendFunc (GLenum sfactor,
GLenum dfactor); |
sfactor must be GL_SRC_ALPHA and
dfactor must be GL_ONE_MINUS_SRC_ALPHA. |
| void glCallList (GLuint list); |
|
| void glClear (GLbitfield mask
); |
The whole zbuffer and the colors are cleared
in any case. The clear color can be redefined, by *not* the initial z value. |
| int glClearColor (GLclampf red, GLclampf
green,GLclampf blue, GLclampf alpha); |
The whole zbuffer and the colors are cleared
in any case. The clear color can be redefined, by *not* the initial z value. |
| void glClearDepth (GLclampd depth); |
The whole zbuffer and the colors are cleared
in any case. The clear color can be redefined, by *not* the initial z value. |
| void glColor | Implemented prototypes: glColor3f, glColor3fv,
glColor4f, glColor4fv |
| void glColorMaterial (Glenum face,
GLenum mode); |
|
| void glColorPointer (GLint size,
GLenum type, GLsizei stride, const GLvoid *pointer); |
|
| void glCullFace (GLenum mode); |
|
| void glDeleteTextures (GLsizei n,
const GLuint *textures); |
|
| void glDisable (GLenum cap); |
(see glEnable for supported flags) |
| void glDisableClientState (GLenum cap); |
(see glEnableClientState for supported flags) |
| void glEdgeFlag (GLboolean flag); | |
| void glEnable (GLenum cap); |
The following flags are handled: GL_CULL_FACE, GL_LIGHTING, GL_COLOR_MATERIAL, GL_TEXTURE_2D, GL_NORMALIZE, GL_LIGHTx, GL_POLYGON_OFFSET_FILL, GL_POLYGON_OFFSET_POINT, GL_POLYGON_OFFSET_LINE GL_DEPTH_TEST is accepted, but it is only used for lines. For all other primitives, Z buffer use is assumed. The DepthMode is hardcoded as GL_LESS (OpenGL default). |
| void glEnableClientState (GLenum
cap); |
No support for GL_INDEX_ARRAY_POINTER or GL_EDGE_FLAG_ARRAY_POINTER |
| void glEnd (void); |

left, GLdouble right, GLdouble bottom, GLdouble top, GLdouble zNear, GLdouble
zFar); |
|
| void glGenLists (GLsizei range); |
|
| void glGenTextures (GLsizei n, GLuint
