Looking for some tips/constructive criticism. Version 1.12

Hey guys, I've been working on a simple graphics demo for the last week or so and was looking for some advice on what I should work on next. EDIT: the new link is at the last post. or here ;) So far I've implemented - a simple batched rendering system for the meshes and few other engine components - a rigging system for moving objects like the camera and meshes on - simple heightmapped terrain - a skybox - a timer class - control of the camera in spaceship-mode I was planning on learning how to use shaders next, and was going to start with multitexturing the terrain. What do you all think? Edit: Oh and could you tell me how well it runs on your systems, and what kind of systems you guys have? Thanks. I've got an x800 pro, so everything runs smooth on my system, lol. :) [Edited by - SiliconMunky on July 16, 2005 8:26:48 AM]

After some busy days at school I finally finished implementing the requested changes. :)

Any thoughts?

It doesn't work :(
Specs: AMD Athlon 1.2GHz, 512MB memory, WinXP, Geforce3.

ErrorLog.log Log Created At: 07/13/05 15:02:46Attempting to initialize the GraphicsEngine - Line:65 - .\GraphicsEngine.cppError! Point size is limited! - Line:121 - .\GraphicsEngine.cppGraphicsEngine Unloaded - Line:52 - .\GraphicsEngine.cpp Log Closed: û

The string after 'Log closed' doesn't paste properly, as it apparently contains random garbage. It seems you're printing random memory there...

Just curious -- what method did you use to render all of the trees? Did you set their positions from each other into their local coordinates and then load them all to one vertex buffer?

Thanks for trying it out Tom! Right now the demo doesn't support the GF3, since it appears that the GF3 doesn't support variable point sprite sizes. Sorry!

About the Log issue. For some reason when doing a my call to localtime is producing garbage data. Something is odd, since it works the first time I call it when the log is created, but not when it's closed.

I'll look into it, thanks!

At loadtime I randomely generate all the positions, then when I go to render them I create a transformation matrix for each tree and set that as the world matrix and then draw that mesh. I loop until all the tree's are drawn.

So to answer your question, no I don't load them all into one vertex buffer. I have one vertex buffer with the mesh data in model space and using that I draw each one into it's own position in world space.

I suppose it would be faster to put them all into one vertex buffer, since their positions are static, and just make one call to draw them. I'll keep that in mind for later.

Hope this helps!

An option to turn of the refresh rate limit would be great.

I'll try it on my geforce6 then :)

Well I've made some more changes. I've added texture splatting to the terrain, as well as updating the particle system with some different blending methods.

That sucks, looks like the geforce4 mx's don't support variable size point sprites.

I suppose its time I post the requirements. DX9, PS1.4, and Variable point sprites. That pretty much means geforce 5200 or better, Radeon 9000 or better.

Thanks for trying.
