PVR AND IRIS 3D

[dciris]

Hi all
I have a question regarding memory allocation.
Recently I have been playing around with Iris 3d's ability load png files on polygons...I know that the dreamcast has roughly 16mb of memory and the pvr has about 4mb (please correct me if I'm wrong) after loading about 20 or so png files I run out of memory in the pvr (The files I am loading are 256 x 256) I assume that Iris 3d is loading these images directly into the pvr and only using the pvr to render the images. I wonder how I can access the other memory within the dreamcast. I want to access the other memory so that I have more space for my png files and to only load them into the pvr when they are requested.

My two thoughts on this are:

1) maybe it is possble to change this in my regular code

2) maybe IrisMaterial.hpp needs to be modified so that the png is loaded into other memory instead of the pvr (I did a search and this function has pvr coding in it that Mr novice over here does not understand)

I would like to keep using Iris 3d if possible because I am comfortable coding within it.

Maybe copying the PNG files to the ramdir and then loading from there would work. But it isn't a good idea to do this to all textures, because you would end up with a lot of redundant data on both RAMs.

[OneThirty8]

I thought the DC had 8MB video memory? I could be wrong on that.
I'm not at all familiar with Iris, but if it is uploading everything to the PVR in one shot, basically, what I can think of two simple-ish options. One would be faster, and the other would consume less of your 16 MB of main memory.
1) You would need a pointer to each of the textures in the PVR, and some equally-sized chunks allocated in main memory. Use the sq_cpy or memcpy function to copy from the PVR to main memory, and then reuse the pointer to the PVR texture to store different data.

2) Basically, the same thing, but you would have a copy of all of your textures in main memory, so you'd only be copying over the ones the PVR needs each frame. This would be faster, but consume more memory. In either case, you'll want to keep track of which textures are available and which are swapped out to main memory.

[GyroVorbis]

I thought the DC had 8MB video memory?

muy correcto!

PS2 is the one with 4 megs.

[Quzar]

You can't use all 8mbs for storage though, afaik, it's more like 4mbs usable for pure storage.

[GyroVorbis]

Yeah, you have whatever is left after you store your vertices and framebuffers.

[BlueCrab]

Yeah, you have whatever is left after you store your vertices and framebuffers.

Actually, the verteces are never stored in VRAM. They're sent directly to the Tile Accelerator. You're left with about 4 or 4.5 MB of VRAM after setting up all the PVR buffers and framebuffers and such.

[dciris]

I must be the sh#!@yist programmer know to man. Yet I am determined to code a quality piece for the dreamcast.

Thanks very much to Fragger and OneThirty8 for your input on this problem.

I have combed the forums and found reference to these functions that could be helpful to this cause

fs_mmap function
memcpy function
fs_unlink

I have realized that I can dump all of my textures into a ram folder that I never knew existed before but I cannot for the life of me put the theory's OneThirty8 mentions into practice.

I have since modified my code to load from ram instead of romdisk
but iris cannot seem to locate the file in ram

Even if my lame attempt worked the problem I'm having would still remain
b/c everything would be loaded from ram to the pvr and it would over flow the pvr again hooray.

I even have trouble understanding the kos manual

example: memcpy(dest, pointer, size);

I understand what pointer is but am unsure how to get an accurate size and destination is size determined by 256 x 256 x 2 =131072? or am I totally off. Other things in the manual seem to baffle me like reference to
file_t hnd, const char among others is there a manual to get me up to speed on these terms? I know experienced programmers look at this and probably say don't try but I am too old and too interested to stop now.

I am reposting my source code in hopes someone can shed light on my problem
i am using kos 1.1.9 and referencing the kos 1.1.8 manual
thanks in advance
