skinned meshes are the bane of my existence

Recommended Posts

hey peeps I am attempting to generate a skinned Mesh based around the d3d example. The code used is a cut down version someone posted a while ago which I’ve add to my attempt at a so called engine. Upon running the code generates a black blob, it should be tiny, grrr! Here is the haphazard code for the gods to decipher… /* * File name: game.cpp * Description: Game code * * */ #include "./game.h" /* include file for game */ //#include "./skinnedMesh.h" /* Convention on return value: 0 means error; 1 means OK */ /*-------------------------------------------------------------------------*\ entry point \*-------------------------------------------------------------------------*/ int CGame :: gameMain(HWND hWnd, MSG * msg) { if ( gameInit(hWnd) ) { gameLoop(hWnd, msg); gameCleanUp(); return 1; } return 0; } /*-------------------------------------------------------------------------*\ Game initialisation \*-------------------------------------------------------------------------*/ int CGame :: gameInit(HWND hWnd) { /* TO DO: add relevant code */ // Initialise graphics module m_cGraphics = CGraphics(); m_cSkinnedMesh = CSkinnedMesh(); if( m_cGraphics.graphicsModuleInit(hWnd)&& m_cSkinnedMesh.Load(&m_cGraphics, "./tiny.x")) { ShowCursor(FALSE); /* hide mouse cursor */ return 1; } return 0; } /*-------------------------------------------------------------------------*\ Game shut-down \*-------------------------------------------------------------------------*/ int CGame :: gameCleanUp() { /* TO DO: add relevant code */ m_cGraphics.graphicsCleanUp(); // release graphics objects ShowCursor(TRUE); /* show mouse cursor */ return 1; } /*-------------------------------------------------------------------------*\ Game loop \*-------------------------------------------------------------------------*/ int CGame :: gameLoop(HWND hWnd, MSG * msg) { /* TO DO: add relevant code */ /* main game loop */ ZeroMemory( msg, sizeof(*msg) ); /* retrieve messages (for e.g. user interaction devices) */ while( msg->message != WM_QUIT ) /* drop out of loop if "quit" message received */ { if( PeekMessage( msg, NULL, 0U, 0U, PM_REMOVE ) ) /* Note: PeekMessage() does not wait for message to be placed in queue before returning (whereas GetMessage() does wait) */ { TranslateMessage( msg ); /* translate keyboard message */ DispatchMessage( msg ); /* dispatch message to window procedure (via Windows) */ } /* game processing */ gameProc(hWnd); } return 1; } /*-------------------------------------------------------------------------*\ Game processing \*-------------------------------------------------------------------------*/ int CGame :: gameProc(HWND hWnd) { /* Terminate if user has pressed the Esc key */ if ( IS_KEY_DOWN(VK_ESCAPE) ) PostMessage(hWnd, WM_DESTROY, 0, 0); else { /* TO DO: add relevant code */ // Clear the backbuffer and the zbuffer m_cGraphics.g_pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET|D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB(255,255,255), 1.0f, 0 ); // Render scene if( SUCCEEDED( m_cGraphics.g_pd3dDevice->BeginScene() ) ) { // Set / update object surface materials and light sources m_cGraphics.setLights(); // Set / update matrices of transformation pipeline m_cGraphics.setTransfPipe(); m_cGraphics.setMaterials(); m_cSkinnedMesh.UpdateMatrices(); m_cSkinnedMesh.DrawFrame(); // End the scene m_cGraphics.g_pd3dDevice->EndScene(); } // Present the backbuffer contents to the display m_cGraphics.g_pd3dDevice->Present( NULL, NULL, NULL, NULL ); //m_cGraphics.render(); } return 1; } CGame::CGame(HWND hWnd, MSG * msg) { gameMain( hWnd, msg); } CGame::~CGame(void) { //Free(); } ------------------------------------------------------------------- /* * File name: graphics.cpp * Description: This sets up a simple rendering pipeline. * *_________________________________________________________________________*/ /*--------------------------------------------------------------------------*\ * NOTE: This file contains API-specific functions * \*--------------------------------------------------------------------------*/ #include <Windows.h> #include <d3dx9.h> #include "graphics.h" /*----------------------------------------------------------------------------\ * | * TYPE DEFINITIONS AND | * DECLARATION OF API OBJECTS USED BY THE APPLICATION | * | *----------------------------------------------------------------------------*/ // define custom vertex type (contains vertex position and normal) struct CUSTOMVERTEX { D3DXVECTOR3 position; // vertex position D3DXVECTOR3 normal; // surface normal at vertex }; // define custom FVF (describes custom vertex structure) #define D3DFVF_CUSTOMVERTEX (D3DFVF_XYZ|D3DFVF_NORMAL) /*----------------------------------------------------------------------------\ * | * TRANSFORMATION PIPELINE CODE | * | *----------------------------------------------------------------------------*/ /* Sets the world, view, and projection transformation matrices.

it works i was been stupid, sorry to bother you guy,

tiny was just out of view.

another qustion though....

should the rootframe be translated by the world position?

and how do i incorporate the .bmp

thanx

AFAIK you should use the World Transformation Matrix

For the Skin you need to load it with D3DXCreateTextureFromFile and SetTexture on the appropriate subset.

the texture file name is in D3DXMATERIAL
