POTranslating many meshes - HLSL
text
Body
copied!<p>Okay forgive me if this is at all vague, but I've been up all night trying to catch up with some coding.</p> <p>I have a reasonably large and defined terrain with minimal optimisations in place and I have just started to introduce predefined meshes (.X objects) which come with materials and textures. Previously I was working in a fixed-function-pipeline approach as I have only recently started working with DirectX9. It has become apparent that FFP is old school and deprecated in DirectX10, so I have been moving relevant code to using a HLSL approach.</p> <p>In my initial approach I had loaded my models into a std::vector container of models and created another std::vector of objects which contain a reference to which model to display. In my render loop, I would iterate this container and check to see if the objects were within the Field-of-view of my camera. If so I would first translate the meshes to their positions, using a SetTransform() call, then DrawSubset().</p> <p>However it has become clear that SetTransform() is not applicable to the HLSL approach; therefore I'm a little stumped to how I can pre-translate these meshes to their relevant positions, or whether I should be translating them within the vertex shader. The meshes are stored within an ID3DXMESH type and it seems that I can access the Index and Vertex Buffer of these meshes; Am I supposed to take the contents of these buffers, translate the contents then draw them? Or am I really going the wrong way about doing this? </p> <p>I am familiar with the Vertex Buffer approach, but not sure what the vertex format is within the mesh itself.</p> <p>Any help would be appreciated as I'm about to tear my eyeballs out.</p> <p><strong>Edit</strong></p> <p>I'll accept Sergio's answer as it pushed me in the right direction although the solution came when I realised in my debug output a line about committing changes.</p> <p><strong>Solution</strong></p> <p>After transforming my mesh I needed to call g_pEffect->CommitChanges();</p>
