Nico de Poel	2344e8ba42	Unrolled quad strip drawing loop to up to three quads at a time, sharing transformed vertices between them. Not actually a performance improvement and I'm not sure why. Sidelining this for now.	3 years ago
Nico de Poel	de12e4269f	Minor stuff	3 years ago
Nico de Poel	32237fc6ec	Fixed a few issues and further optimized the quad drawing code.	3 years ago
Nico de Poel	4f2d70cc82	Added some macros to make the optimized drawing code more readable, and applied the same optimization to water drawing.	3 years ago
Nico de Poel	74a36f0938	Found a 10% performance boost by simply reordering data access when filling in polygon data, and by blitting UV and RGB values with a single copy.	3 years ago
Nico de Poel	542a81b68c	Draw lava, slime and teleporters as liquids, but not transparent.	3 years ago
Nico de Poel	314b52e99e	Added a separate CLUT for transparent surfaces, and set semi-transparency mode on water polygons.	3 years ago
Nico de Poel	ae080953f7	Rewrote the other face drawing functions to ditch the vertex copying stage too.	3 years ago
Nico de Poel	be7eb87685	Ditched the copy-to-scratch-RAM step for drawing textured faces, which apparently is no longer needed to run on real hardware. Simpler code, less work to do, better performance. An all-round win.	3 years ago
Nico de Poel	a8d3bf567b	First pass at leaf-based rendering order: - Sort leafs first into a linked list, before drawing their faces - Depth value for faces is determined by the leaf order, OT position is calculated once per leaf - Removes the need for per-primitive depth calculation & check, so those are removed - Moved primitive buffer check out of the primitive drawing routines and to the start of each face drawing function - Triangle drawing routines now only draw a single triangle, no loops involved - Simplified drawing routines where possible - Face drawing is still happening in back-to-front order, so this needs another good look at	3 years ago
Nico de Poel	812bcb6a63	Some micro-optimizations in the face drawing code. The PS1 really does favor simple counters over pointer arithmetic.	3 years ago
Nico de Poel	85a8b332c5	Some reorganization of face drawing code; allow better separation between drawing methods, and require the "enable texturing" check only once ahead of drawing.	3 years ago
Nico de Poel	c9bee9d500	Draw water surfaces as unlit textured polygons	3 years ago
Nico de Poel	73903474e4	Moved polygon drawing routines into a separate header file	3 years ago
