 Posted: Thu Sep 03, 2009 6:23 am Post subject: [pspgu] help with index-list |
 |
|
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 draw a vertex let's say with the position of the first vertex(x1, y1, z1) and the texture coordinatesof the second(u2, v2) and the color of the third(c3). Is it possible to do that with index-list? and if the anszer is yes, how? The vertex array must be like that:
{x1, y1, z1, u1, v1, c1,
x2, y2, z2, u2, v2, c2 ... }
or
{x1, y1 , z1, x2, y2, z2
u1, v1, u2, v2,
c1, c2}
??????????????????/ |

| Stop posting and bumping the same question. You've posted two possible answers -- can't you just try them and see? |

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) |

well, i tried to draw a torus unsuccssefly
| Code: |
/* Initialisation function */
vertices = (TCNPVertex*) malloc(sizeof(NPVertex) * 100);
indices = (unsigned short*) malloc(sizeof(unsigned short) * 9 * 9);
generateTorusTCNP(10, 10, 10, 1, vertices, indices);
texture = loadImage("texture.png");
/* Draw Function */
// transformations
rot += 0.01f;
sceGumRotateY(rot);
ScePspFVector3 pos = { -0, -0, -10 };
sceGumTranslate(&pos);
//texture
sceGuTexMode(GU_PSM_8888, 0, 0, 0);
sceGuTexFunc(GU_TFX_REPLACE, GU_TCC_RGB);
sceGuTexFilter(GU_LINEAR, GU_LINEAR);
sceGuTexImage(0, texture->textureWidth, texture->textureHeight, texture->textureWidth, (void*)texture->data);
// draw
sceGumDrawArray(GU_TRIANGLES, TCNP_VERTEX_FORMAT, 10*10, indices, vertices); |
But i got unexcepted result :( [/code] |
