Models Vertex

[djoker]

hi ppl

i will try my best 2 explain my problem
sorry my English

i try to load new models to IRR and
all models have this way +-

Code: Select all

for(int i = 0; i < g_3DModel.numOfObjects; i++)
{
t3DObject *pObject = &g_3DModel.pObject[i];

glBegin(GLTriangles);					
// Go through all of the faces (polygons) of the object and draw them

for(int j = 0; j < pObject->numOfFaces; j++)
    {
   // Go through each corner of the triangle and draw it.

for(int whichVertex = 0; whichVertex < 3; whichVertex++)
    {

// Get the vertex index for each point of the face
int vertIndex = pObject->pFaces[j].vertIndex[whichVertex];

// Pass in the current vertex of the object (Corner of current face)
glVertex3f(pObject->pVerts[ vertIndex ].x, pObject->pVerts[ vertIndex ].y, pObject->pVerts[ vertIndex ].z);

				}
			}

		glEnd();								
// End the drawing
	}

i get the triangles this way

int vertIndex = pObject->pFaces[j].vertIndex[whichVertex];
pObject->pVerts[ vertIndex ]//vertex

we have all triangles .
on IRR we draw by index (drawIndexedTriangleList)

in this code we get the triangle by index
my problem is how i pass the triangles and index

Vertices[0] = video::S3DVertex(
pObject->pVerts[ vertIndex ].x, pObject->pVerts[ vertIndex ].y, pObject->pVerts[ vertIndex ].z,
pObject->pNormals[ vertIndex ].x, pObject->pNormals[ vertIndex ].y, pObject->pNormals[ vertIndex ].z,
video::SColor(255,255,255,255),
pObject->pTexVerts[ coordIndex ].x, pObject->pTexVerts[ coordIndex ].y);

driver->drawIndexedTriangleList(&Vertices[0], 3, ?????, 3);


i next irr version irr must have drawTringleList

you should have a look at tutorial 3

dude my pronb is not in IRR


i try the code from gametutorial

i just want 2 render external models

on tut 2 you have the indices define

u16 indices[] = { 0,2,3, 2,1,3, 1,0,3, 2,0,1 };

So what's your problem then? Just draw the index vertices from the example and you should understand the mechanism. If you just draw independent triangles without using vertices twice you just make the indices 0,1,2,...,n for n vertices.

hybrid i love you
