Re: Wiki feedback

Sorry by found it i just mean i had found the previous time i had the same issues. It was a muc more successful effort last time

Then i started working backwards to see just how early it failed.
The answer... very early

Re: _asm Anomaly

OK So i need to preserve my fregs and integer regs when i make each call? I've preserved the fregs and it assembles and runs, but my angle calls are getting knackered up, so between push and pop stack routines, my variables are essentially useless. Currently my clobber list as it were is all fregs, ...

Re: _asm Anomaly

ATM i pushed and popped and its working fine now.
Its from a .s file so its probably only certain regs.

I'll try it with KOS too.

The speed... isnt bad atm
we'll see how much it comes down

OK I have some matrix code in asm which i am running before my render code. Trouble is that when the matrix code is in, the OP poly list doesnt display. This would sggest somenow that the registers i am using for the matrices are interfering with the prefecth or the SQ pointer. i should maybe use ma...

Re: Script for automatically converting textures to best for

Texconv is now working and i fixed some of the demo code to load dtex files including paletted ones. It currently loads up to 32 4BPP palettes to the first 512 and 2 8BPP palettes to last 512 I may do a version where you can specify a palette index when its called. In fact i think i will, or 16 and ...

PVR DMA Vertices

Hi Guys

I've seen much discussion of pvr dma for vertices but i'm not quite understanding it.

Is there any sample code anywhere that i could see to try to get a grip on it?
Just a simple demo?

Cheers

USB to Serial Port Adapter - Use as Dumb Terminal

Hi Guys I got a USB to serial port adapter for use with the Coders Cable when i dont have access to a docking station. Its a fairly stratigtforward USB to RS232 via CH340. However, no matter what COM port i set it to, it never sees the DC. Indeed the DC LOad on the DC never gets the white line down ...

Re: TR Polys - Fixed(p_cxt.depth.comparison = PVR_DEPTHCMP_G

I have been playing around a bit, i think thats how i got it messed up... silly but sorted out now, and yes using pvr_poly_cxt_txr() and then changing the bits i want to fiddle with. I'm making good progress now, opaque, punchthrough, transluscent, modifiers all working... now to decide how much of ...

Re: TR Polys?

Nevermind it helps if i apply the same

p_cxt.depth.comparison = PVR_DEPTHCMP_GEQUAL;

to each poly context.

Re: TR Polys?

I'm not sure i'm understanding.

My issue is that my TR poly is appearing on top of my opaque poly, no matter what their respective z's.

This is an issue if for example i wish to display a translucent fire which is partly obscured by a wall.
