Please find listed below complete details of
functions supported within our various MiniGL implementations.
At this time no technical support is available for any of these drivers, although we
will endeavour to read suggestions and comments sent to the following email address.

| Problems |
Slow :-) |
Slight problems with transparency (our
fault :-)). |
General compatibility problems with
interfacing with windows (MSI95 limitation). |
Fog doesn't work with color controlled
transparency (hardware limitation). |
|
General limitations:
- Only 16 bit hicolor modes supported
- Mostly only rasterization functions supported
- No 2d/point/line functions supported
- No arrays/precompiled arrays (yet)
- Simplified lighting model (no spotlights, only front material used)
- GL_MODULATE and GL_REPLACE texture modes only
- Supported only GL_REPEAT texture mode
Unsupported functions do nothing and display short message on debugging terminal. |
