- Yes, I did know about that part (although I had no actual formulaic details, so
- thanks for that) - but there are 2 reasons I decided to leave the sky mapping
- linear.
-
- 1) Bad Mood's floor & ceiling textures are drawn in rows instead of columns in
- order to gain back as much time as possible during the rendering pass. The extra
- work required from the DSP to achieve this method is not as great as the time
- lost rendering lots of stacked columns. I guess you can imagine how slow it will
- be to perform this indexing function for each pixel of each row. Even a pregenerated
- lookup will roughly halve the rendering speed.
-
- 2) It looks odd on the PC when you have mountains or buildings in the sky texture.
- It's fine for clouds, but mountains 'stretch' at the edges and look like they are
- painted onto a big rubber band. I guessed that if it looked suss on my PC anyway,
- then it definitely was not worth the expense in rendering time for BM.
-
- I suppose it can always be added if it's required, but I don't think it's worth the
- cost in rendering time myself - especially considering how little it adds to the
- game in general.
-
- I do however agree that it is not correctly mapped anyway - the positioning needs
- adjusted vertically. I forget to do this every time I upload a new version. :)
-
- Doug.
