Hi Everyone
i am trying to render a pretty basic static mesh that has no y value in D3D9. (it will actually be a bruteforce terrain method but just for testing i dropped the y value for simplicity)
here is some code
init function:
struct Vertex3f
{
float x,y,z;
};
Vertex3f *vertices;
short *indices;
vertexcount = m_iSize * m_iSize *3;
vertices = new Vertex3f[vertexcount];
indicecount = (m_iSize-1)*(m_iSize-1)*6;
indices = new short[indicecount];
//Build our vertex array
for(int z=0; z<m_iSize; z++ )
{
for( int x=0; x<m_iSize; x++ )
{
vertices[z*m_iSize+x].x = x*m_fStep;
vertices[z*m_iSize+x].y = 0;
vertices[z*m_iSize+x].z = z*m_fStep;
}
}
//Build our indice array
int i=0;
for(int z=0; z<m_iSize-1; z++ )
{
for( int x=0; x<m_iSize-1; x++ )
{
//triangle 1
indices = x +(m_iSize *z);
i++;
indices = x + (m_iSize * (z+1));
i++;
indices = (x+1) + (m_iSize * (z+1));
i++;
//triangle 2
indices = (x+1) + (m_iSize * (z+1));
i++;
indices = (x+1) + (m_iSize * z);
i++;
indices = x +(m_iSize *z);
i++;
primitivecount+=2;
}
}
render function:
m_d3D9dev->SetFVF(D3DFVF_XYZ);
m_d3D9dev->DrawIndexedPrimitiveUP(D3DPT_TRIANGLELIST,0,vertexcount,primitivecount,indices,D3DFMT_INDEX16,vertices,sizeof(Vertex3f));
running this in debug mode gives me this error
First-chance exception at 0x7c80c851 in testdx.exe: 0xC0000005: Access violation reading location 0x00bf1000.
Direct3D9: (ERROR) :Invalid index data pointer
any ideas what i am doing wrong?
