naja, das lighting is on
| C++: |
GLfloat LightAmbient[]= { 0.5f, 0.5f, 0.5f, 1.0f };
GLfloat LightDiffuse[]= { 1.0f, 1.0f, 1.0f, 1.0f };
GLfloat LightPosition[]= { 0.0f, 0.0f, 2.0f, 1.0f };
glLightfv(GL_LIGHT1, GL_AMBIENT, LightAmbient);
glLightfv(GL_LIGHT1, GL_DIFFUSE, LightDiffuse);
glLightfv(GL_LIGHT1, GL_POSITION, LightPosition);
glEnable(GL_LIGHT1);
|
und GL_TEXTURES_2D wird in der draw() der modelclass gesetzt
| C++: |
void ModelMS3D::draw()
{
GLboolean texEnabled = glIsEnabled( GL_TEXTURE_2D );
// Draw by group
for ( int i = 0; i < m_numMeshes; i++ )
{
int materialIndex = m_pMeshes[i].m_materialIndex;
if ( materialIndex >= 0 )
{
glMaterialfv( GL_FRONT, GL_AMBIENT, m_pMaterials[materialIndex].m_ambient );
glMaterialfv( GL_FRONT, GL_DIFFUSE, m_pMaterials[materialIndex].m_diffuse );
glMaterialfv( GL_FRONT, GL_SPECULAR, m_pMaterials[materialIndex].m_specular );
glMaterialfv( GL_FRONT, GL_EMISSION, m_pMaterials[materialIndex].m_emissive );
glMaterialf( GL_FRONT, GL_SHININESS, m_pMaterials[materialIndex].m_shininess );
if ( m_pMaterials[materialIndex].m_texture > 0 ) {
glBindTexture( GL_TEXTURE_2D, m_pMaterials[materialIndex].m_texture );
glEnable( GL_TEXTURE_2D );
} else {
glDisable( GL_TEXTURE_2D );
}
} else {
// Material properties?
glDisable( GL_TEXTURE_2D );
}
glBegin( GL_TRIANGLES );
{
for ( int j = 0; j < m_pMeshes[i].m_numTriangles; j++ )
{
int triangleIndex = m_pMeshes[i].m_pTriangleIndices[j];
const Triangle* pTri = &m_pTriangles[triangleIndex];
for ( int k = 0; k < 3; k++ )
{
int index = pTri->m_vertexIndices[k];
glNormal3fv( pTri->m_vertexNormals[k] );
glTexCoord2f( pTri->m_s[k], pTri->m_t[k] );
glVertex3fv( m_pVertices[index].m_location );
}
}
}
glEnd();
}
if ( texEnabled )
glEnable( GL_TEXTURE_2D );
else
glDisable( GL_TEXTURE_2D );
}
