can you render point sprites with transformed vertices?

I'm trying to make a particle system in direct3d9 using point sprites. When I use D3DFVF_XYZ|D3DFVF_DIFFUSE|D3DFVF_POINTS|D3DFVF_DYNAMIC as the vertex format it works, but when I switch D3DFVF_XYZ for D3DFVF_XYZRHW nothing shows up. I haven't read anything in Microsoft's documentation that forbids using transformed vertices, but I haven't done a very thorough reading. The only problem I could think of might be point sprite scaling but even when I turned that off it still didn't work.

Thats because you're rendering in completely different spaces. You've just admitted to having done no research which is precisely what I told you to do in the prior thread when you were having problems.


You need to read THOROUGHLY about the transformation pipeline.....
Direct3D does not hold your hand through this.

What prior thread are you talking about? This is the only thread I've ever made about anything that's direct3d related. Anyway thanks for the advice.

What would he gain from asking the same question under a different username?

For a 15 year old self conscious teenager to not appear to be a moron. Which is ironic because asking questions is exactly how you learn anyways. I have a sneaky suspicion that I know exactly who this is. He's on my skype. It's possible that it's not the same person, but given my critical nature, I'm doubtful :]

Ask yourself this: I've been on the forum for 4 years or so. I have NEVER seen a SINGLE question asked directly about DX9, then two about the same topic (Flexible Vertex Format or FVF) in particular to DX9 within a day or two. I mean, c'mon. That's SOME statistical anomaly, no? :P

Perhaps, but the accounts do use two different ISPs to log on.. not difficult but still a lot of effort just to spoof programming forums with a couple hundred users. The way that he responded to your accusation was a bit suspicious though.. and he has yet to say anything since.

I would say its absolutely uncanny to say the least. Well, either way...this is good. Any chance I can get to spur on DX development is a chance I'll take...

...considering who I believe this to be, I wouldn't doubt the effort though...
