PointSprites

[thelyingspy]

Hello!

I'm trying to get point sprites going using the MegaSDK. Unfortunately, whenever I try to render even 1 point sprite, it slows to 1 FPS.

I have tried the Micorosft SDK PointSprites.exe, and it worked OK.

I have created my VertexBuffer with D3DUSAGE_POINTS.

I think it's something to do with Hardware or Software Vertex Processing, I don't want to hack through all the tuff stuff in the SDK to find out though.

Could someone tell me whats going on at all?

Thanks,
TLS

Hi,

Yep, I worked it out.

A combination of...

GetDevice()->SetRenderState( D3DRS_POINTSCALEENABLE, true );

...and...

// finally, create the device:
if(FAILED(hRes = m_lpD3D->CreateDevice(
ordinal_adapter,
D3DDEVTYPE_HAL,
m_hwnd,
//(m_caps.DevCaps & D3DDEVCAPS_HWTRANSFORMANDLIGHT) ? D3DCREATE_MIXED_VERTEXPROCESSING : D3DCREATE_SOFTWARE_VERTEXPROCESSING,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&m_d3dpp,
&m_lpDevice ) ) )

...did the trick.

Thanks Everyone!
