Drawing Primitives with DXUT

foursticksj · 2014-01-09T18:26:02

Has anyone had any problems drawing primitives using the DXUT framework?I have two programs that do exactly the same thing, drawing a triangle to the screen. One uses DXUT and the other does not. The program that does not use DXUT renders the triangle fine, while using DXUT nothing gets drawn.Not using DXUT:------------------------------------------------------------------------------void render(){ d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0); d3ddev->BeginScene(); // create the vertices using the CUSTOMVERTEX struct CUSTOMVERTEX vertices[] = { { 400.0f, 62.5f, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 0, 255), }, { 650.0f, 500.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 150.0f, 500.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), }, }; LPDIRECT3DVERTEXBUFFER9 v_buffer = NULL; d3ddev->CreateVertexBuffer(3*sizeof(CUSTOMVERTEX), 0, CUSTOMFVF, D3DPOOL_MANAGED, &v_buffer, NULL); VOID* pVoid; v_buffer->Lock(0, 0, (void**)&pVoid, 0); memcpy(pVoid, vertices, sizeof(vertices)); v_buffer->Unlock(); d3ddev->SetFVF(CUSTOMFVF); d3ddev->SetStreamSource(0, v_buffer, 0, sizeof(CUSTOMVERTEX)); d3ddev->DrawPrimitive(D3DPT_TRIANGLELIST, 0, 1); d3ddev->EndScene(); d3ddev->Present(NULL, NULL, NULL, NULL);}------------------------------------------------------------------------------Using DXUT------------------------------------------------------------------------------void GameApp::vOnFrameRender (void) // render callback{ DXUTGetD3D9Device ()->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0); DXUTGetD3D9Device ()->BeginScene (); CUSTOMVERTEX vertices[] = { { 400.0f, 62.5f, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 0, 255), }, { 650.0f, 500.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(0, 255, 0), }, { 150.0f, 500.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), }, }; LPDIRECT3DVERTEXBUFFER9 v_buffer = NULL; DXUTGetD3D9Device ()->CreateVertexBuffer(3*sizeof(CUSTOMVERTEX), 0, CUSTOMFVF, D3DPOOL_MANAGED, &v_buffer, NULL); VOID* pVoid; v_buffer->Lock(0, 0, (void**)&pVoid, 0); memcpy(pVoid, vertices, sizeof(vertices)); v_buffer->Unlock(); DXUTGetD3D9Device ()->SetFVF(CUSTOMFVF); DXUTGetD3D9Device ()->SetStreamSource(0, v_buffer, 0, sizeof(CUSTOMVERTEX)); DXUTGetD3D9Device ()->DrawPrimitive(D3DPT_TRIANGLELIST, 0, 1); g_HUD.OnRender( m_timer.getDelta ()); DXUTGetD3D9Device ()->EndScene();}------------------------------------------------------------------------------I know the verticies should be declared in a initialization function, Im just simplifying the code for now. Help with this would be greatly appreciated.

Cool, I got it up.

All I really had to do was change the z coordinated to 0s and you can see the triangle. Of course, this probably has to do with the way the camera was set up.

Thanks for all the help

Just out of curiosity, why would the triangle disapear when I add the z coordinate?
I'm planning on just doing 2D stuff, but I might need to do some rotation. Is there some Z buffer function I need to call?

Hmm, nevermind. I forgot to remove the RHW

Hi!

Can you show me the variables declarations, I have the same issue, I have my code working without DXUT, I can rotate it, an do some basic stuff.

Now I want to modify the code and take it to DXUT. Can you help me with the 'translation'?
