up

well, i tried to draw a torus unsuccssefly /* Initialisation function */ vertices = (TCNPVertex*) malloc(sizeof(NPVertex) * 100); indices = (unsigned short*) malloc(sizeof(unsigned short) * 9 * 9); genera...

if those functions are not called, gu will use the RAM?

i didn't find aything iterresting. A part the vertex sample wich is a little bit complicated and doesn't exactly what i want it to do(it's just calculating, doesn't render anything at the screen)

I see sometimes in pspgu initialisation this lines: void* fbp0 = getStaticVramBuffer(BUF_WIDTH,SCR_HEIGHT,GU_PSM_8888); void* fbp1 = getStaticVramBuffer(BUF_WIDTH,SCR_HEIGHT,GU_PSM_8888); void* zbp = getStaticVramBuffer(BUF_WIDTH,SCR_HEIGHT,GU_PSM_4444&#41...

anyone to help?

i tried both but no one worked: http://pastebin.archlinux.fr/358207

Thank's all, it's clearer know

Hi, Because of the lack of documentation of using index-list, i need your help. Imagine i have three vertices: V1: position: x1, y1, z1; texture: u1, v1; color: c1; V2: position: x2, y2, z2; texture: u2, v2; color: c2; V3: position: x3, y3, z3; texture: u3, v3; color: c3; /* and so on */ I want to d...

i steal don't understand, if a data is 32bits aligned, it will be 16bits aligned. So why in every tutorial for PSP we use memalign(16, ...)?
Also, the list passed to sceGu, f don't specify "__attribute__((aligned(16)))" no vertexis shown at the screen

Hi, first eccuse my bad english I wanna know if the index array must point to a vertex or to ther vertex composants. I mean, if my vertex tab is like that: vertex[] = { { u, v, color, x, y, z },// vert 0 { u, v, color, x, y, z },// vert 1 // .... { u, v, color, x, y, z }// vert n } and my index arra...

I red in the doc of sceGuDrawArray:

Every vertex must align to 32 bits, which means that you HAVE to pad if it does not add up!

ok thanks

thanks for you reply.
so i must understand that i always have to use memalign(16, whatever) instead of new/malloc?

i was talking about 3d physics engin ...
i couldn't find ode in pspliraries

Hi,
Is there any physics engine port for PSP?

Hi, I red in many tutorial that i should use memalign to allocate memory for my vertices. for example, this is my Vertex class: struct Vertex { float u, v; unsigned int color; float x, y, z; }; this is how i should allocate memory: vertices = (Vertex*) memalign&...
