LTM DIRECTDRAW

using the core of the ltm dos project, LTMdd implements the optimized gouraud-shaded texture-mapped drawing routines in DirectDraw.

the core itself has been extended to use 16bit and 32bit color lookup tables (greatly enhancing the image quality) but the textures still are limited to 8bit images.

OBJECT IMPORT AND SKINNING

a basic interface was developed to import, texture map and smooth dxf-polygon models.

The dxf-importer sorts the faces of the object to create optimized BSP-trees. The algorithm used does have some drawbacks: every object is considered to have a convex surface, in other words, no object may intersect the 'shrinkwrap' of another object in any way. Placing a box between the legs of a (single object) table would cause visual errors. To implement a feature like that, the legs of the table should be defined as separate objects...
