- Here are listed the functions that TinyGL understands with the known
- limitations. The non mentionned functions are *not* implemented and
- must not be used.
-
-
- ************ glEnable / glDisable
-
- - 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 *cannot* be disabled. The
- DepthMode is hardcoded as GL_LESS (OpenGL default).
-
- ************ glShadeModel
-
- OK.
-
- ************ glCullFace
-
- OK.
-
- ************ glPolygonMode
-
- OK.
-
- ************ glBegin
-
- No tests are performed to prevent some functions of being executed
- between glBegin/glEnd.
-
- ************ glEnd
-
- OK.
-
- ************ glVertex
-
- Some prototypes are not implemented.
-
-
- ************ glColor
-
- Some prototypes are not implemented.
-
- ************ glNormal
-
- Some prototypes are not implemented.
-
- ************ glTexCoord
-
- - Some prototypes are not implemented.
-
- - The Matrix transformation is not applied yet.
-
- ************ glEdgeFlag
-
- OK. The edge handling has to be tested, although it is not much useful
- in TinyGL.
-
- ************ glMatrixMode / glLoadMatrixf / glLoadIdentity / glMultMatrixf /
- glPushMatrix / glPopMatrix / glRotatef / glTranslatef / glScalef /
- glFrustum
-
- - The prototypes with doubles are not implemented.
-
- ************ glViewport
-
- GlViewport calls a function pointers to tell glx (or another display
- system) to resize the Z buffer and the ximage. Made optional in
- version 0.2.
-
- ************ glGenLists / glIsList / glNewList / glEndList / glCallList
-
- OK.
-
- ************ glClear / glClearColor / glClearDepth
-
- The whole zbuffer and the colors are cleared in any case. The clear color
- can be redefined, by *not* the initial z value.
-
- ************ glRenderMode
-
- Only the modes GL_RENDER and GL_SELECT are implemented.
-
- ************ glSelectBuffer / glInitNames / glPushName / glPopName / glLoadName
-
- OK.
-
- ************ glGenTextures / glDeleteTextures / glBindTexture
-
- OK. These functions should be used to get the maximum performance with
- TinyGL.
-
- ************ glTexImage2D
-
- The function accepts only RGB UNSIGNED_BYTES bitmaps. They are
- internally resized to 256x256 so you'd better use that size. No
- mipmapping is implemented although it will come if asked. No borders
- are implemented.
-
- ************ glTexEnvi
-
- The only supported mode is GL_DECAL, although others are planned if
- asked.
-
-
- ************ glTexParameteri
-
- The other prototypes are not implemented. Only the follwing mode are
- implemented:
-
- glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
- glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
- glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
- glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
-
- ************ glPixelStorei
-
- The pixels are alware byte aligned.
-
- ************ glMaterialfv / glMaterialf / glColorMaterial
-
- OK.
-
-
- ************ glLightfv / glLightf / glLightModeli / glLightModelfv
-
- OK. The OpenGL lightening is implemented but not optimized.
-
-
- ************ glFlush
-
- Ignored.
-
- ************ glHint
-
- Ignored.
-
- ************ glGetIntegerv
-
- - only GL_VIEWPORT, GL_MAX_MODELVIEW_STACK_DEPTH,
- GL_MAX_PROJECTION_STACK_DEPTH, GL_MAX_LIGHTS, GL_MAX_TEXTURE_SIZE,
- GL_MAX_TEXTURE_STACK_DEPTH
-
- ************ glGetIntegerv
-
- - only GL_TEXTURE_MATRIX, GL_PROJECTION_MATRIX, GL_MODELVIEW_MATRIX,
- GL_LINE_WIDTH, GL_LINE_WIDTH_RANGE, GL_POINT_SIZE, GL_POINT_SIZE_RANGE
-
- ************ glPolygonOffset
-
- - only API implemented.
-
- ************ glEnableClientState, glDisableClientState,
-
- - No support for GL_INDEX_ARRAY_POINTER or GL_EDGE_FLAG_ARRAY_POINTER
-
- ************ glVertexPointer, glNormalPointer,
- glColorPointer, glTexureCoordPointer
-
- - OK
-
- ------------------------------------------------------------------------------
-
- TinyGL GLX emulation:
-
-
- ************ glXQueryExtension
-
- Returns always True
-
- ************ glXChooseVisual
-
- Only 8 bit Pseudocolor or 16 bit Truecolor Visual are accepted. The
- attribute list is ignored.
-
- ************ glXCreateContext
-
- The sharing is not implemented although the code could handle it.
-
- ************ glXDestroyContext
-
- OK.
-
- ************ glXMakeCurrent
-
- Not all the syntax is supported yet, in particular with the 'NULL' or
- 'None' parameters.
-
-
- ************ glXSwapBuffers
-
- OK.
-
- ************ glXWaitGL / glXWaitX
-
- Ignored.
