Ian Curtis	c039d08c03	Add supersampling anti-aliasing ... Late christmas present. Due to the way alpha works on the model3 adding regular anti-aliasing doesn't really work. Supersampling is very much a brute force solution, render the scene at a higher resolution and mipmap it. It's enabled via command line with the -ss option, for example -ss=4 for 4x supersampling or by adding Supersampling = 4 in the config file. Note non power of two values work as well, so 3 gives a very good balance between speed and quality. 8 will make your GPU bleed, since it is essentially rendering 64 pixels for every visible pixel on the screen.	2023-12-26 18:25:03 +00:00
Ian Curtis	bf4d725970	Smooth texture repeat makes no sense for alpha/contour textures with pixel dilate. HW seems to treat them as non smooth anyway. Also implement some line of sight stuff, used by Scud. Really need to check the threading/synchronisation of the register reads but it basically works.	2018-10-19 20:59:46 +00:00
Ian Curtis	eb798ed15e	Star wars is the only game to pass unsigned fixed shaded values (per vertex brightness) to the renderer. Originally we thought that the specular flag would turn on unsigned values since it's the only game to set specular with these polys, but this logic turned out to be incorrect. The JTAG interface seems to config the GPU to turn on this functionality. (Harry Tuttle)	2017-10-05 19:15:00 +00:00

Ian Curtis	ff624afb4d	The mipmap data in some games seems to being sent behind the base textures, and when the base textures are bound and created the mipmap chain is not yet valid in memory. To fix this, we invalidate the base textures, when the mipmap chain is updated.	2017-03-25 00:06:24 +00:00
