Please Test! render2texture & DDS CopySurface

Blitz3D Forums/Blitz3D Userlibs/Please Test! render2texture & DDS CopySurface

Tom (Posted 2006) [#1]

Hi all, BACKUP IMPORTANT WORK BEFORE USING! Here's a beta version of my Render 2 Texture and a new CopySurface() that works with .dds textures. Sample source included, please post feedback/bugs and GFX card specs!!! It requires you install a userlib. Unpack the DX7DLL_8thAug06 ZIP into Blitz3D\Userlibs\ (there should be dx7test.dll and dx7test.decls in there) Sorry if you were using a previous version of this DLL and it messes up existing projects, but this version is a lot more refined (read: less hacky! :) http://www.tomspeed.com/beta/ Notes: Blitting TO a DDS texture is slower than blitting to a normal texture, although blitting FROM DDS textures is quick. CopySurface() works with regular Blitz3D textures too, though for some strange reason DX says blitting from a regular masked or Alpha B3D texture is unsupported (huh?) Have fun and see if you can break the new functions! Cheers Tom

GeForce 7800 GTX: 1 - Simple Render to Texture.bb Worked! Fps 450-500+ 2 - RT Performance.bb Bombed! Got "Function 'createrendertexture' not found" 3 - EndGraphics.bb Worked! Memory usage was constant after pressing "space" - which "reset" the scene perfectly. Mouse button stuff worked too. 4 - Using a quad mesh and RT for screen FX.bb Worked! Took me a while to "get" what "space" does... CopySurface DDS.bb [edit] Worked! Duh... can I be so dum... after installing 1.97 it worked MUCH better :)

Tom (Posted 2006) [#3]

hehe yeh, 4 isn't obvious if the quad is perfectly lined up. 2 is my fault, I forgot to change references to CreateRenderTexture to UserRenderTexture in the source, I'll update it now :)

This is a work machine not a 3D graphics monster but thought I'd try anyhow. I'll post a Radeon X1600 PRO report tonight. 1 - Simple Render to Texture.bb 35 FPS 2 - RT Performance.bb <edit> 34 FPS 3 - EndGraphics.bb 35 FPS 4 - Using a quad mesh and RT for screen FX.bb 28 FPS GFX: Intel 82865G

Hi Tom, another great work! 1 - Simple Render to Texture.bb Worked! 2 - RT Performance.bb Worked! 3 - EndGraphics.bb Worked! 4 - Using a quad mesh and RT for screen FX.bb Worked! CopySurface DDS.bb Copy surface 1 brings texture errors Copy surface 2 works fine! Thank you for your hard work! ATI Radeon 9100 64 MB VRAM / Win98se

What's this stuff for? Is it purely for doing what we can already do, but with a DDS?

Boiled Sweets (Posted 2006) [#7]

You cannot currently render to a texture.

Tom (Posted 2006) [#8]

Puki: Normaly when you call RenderWorld() everything is drawn to the backbuffer, the backbuffer being a 'render target'. Now, hardware permitting, you can create a texture that you can set as a render target, then when you call RenderWorld() it draws the scene directly to the texture. If you had code that done this: RenderWorld() CopyRect 0,0,800,600,0,0,BackBuffer(),TextureBuffer(myTexture) You could replace it with: SetRenderTarget myTexture RenderWorld() It's a lot quicker And CopySurface() is primarily if you want to copyrect using DDS textures, as Mark hasn't enabled it at this time.

This thing seems to clash with vardx7 decls and dll so I removed them. Right, looks like I am going to add in mirrors to Oblivion then - Bethesda didn't have mirrors.

Hi Tom, 1 - Simple Render to Texture.bb 796 FPS - runs fine. 2 - RT Performance.bb 270-814 FPS - runs fine too! 3 - EndGraphics.bb Worked too! 4 - Using a quad mesh and RT for screen FX.bb 525-745 FPS. runs fine too! CopySurface DDS.bb Copy surface 1 brings artifact errors Copy surface 2 works pretty fine. Tom, i think you should teamup with BRL to kick B3D to its real limits!! All tests performed on my work/game machine. details see sig.

oops, i found out that the old dx7dll works fine with EnableAnisotropic. The new one doesn't.

Mustang (Posted 2006) [#13]

Pleased that Mustang has finally got what he wanted :) :)) Last few days have been very good to me, can't deny that! But there are still tangent space normalmaps and shadows (stencils, whatever) on my wishlist. After those I'm out of ideas... and can't blame the tools anymore for not finishing my game ;P

Hi, All is working on the laptop, very cool! For the EndGraphics thingie, you can use clearworld as well.

Tom (Posted 2006) [#19]

looking good! Check my thread in Blitz3D programming for a cute bump mapping demo :)

puki (Posted 2006) [#20]

Okey-dokey.

puki (Posted 2006) [#21]

What thread?

Tom (Posted 2006) [#22]

I think I can make Blitz3Ds own environment maps renderable too, then you can bypass the copyrect step when doing realtime cubemaps. Puki: Shhh!

puki (Posted 2006) [#23]

What about those stencil shadows you were working on? I need those too.

Trixx (Posted 2006) [#24]

All four examples worked OK on GF1 GTS 32 MB / P4 2.4 / 512MB / WIN XP And... thanks Tom for all your efforts...
