DirectX8 - Cheers to Z for billboard code - It works :)

Z

Just a note to say ty for ur help wiv BB's. The altered Fixed Y Axis BB function works a treat now. I have throughly tested everything and its a big thumbs up all round.

I kinda needed a break from the graphics side of things so I have been doing DirectSound and the like but back to graphics now :).

If any1 wants some good BB code I have attached it here. NB : The screen res is set to 1600 x 1200 u may need to change it.

PS U will need to alter the code slightly if u wanna see textures, I have removed them to keep the dl size smaller. This code only attempts to illustrate billboarding.

PS This code has a lot of alpha blending stuff in it since i was using textures with alpha values in them. Also I have just noticed that the draw order must be calculated using D3DXVec3Project if using alpha blending. This info is only relevant to alpha blending not billboarding. Any questions feel free to ask.

Hey, sure thing =).

One note, when using the billboards for particle systems, you might notice the alpha blending artifacts (things not being drawn correctly). You CAN sort the particles from back to front, but this would be a lot of work. You can cheat, and turn off Z writing (D3DRS_ZWRITEENABLE), draw your billboards, and turn Z writing back on.
