LINE2D/LINE3Dの負荷が高い

[tanitta]

• 推測される原因 描画のたびにVBをLockしてる（RigidMain.cpp l:1321参照）
• 考えられる解決策 Luaのtableに座標を入力して、一回のLockで書ききる、_LINE2DEX/_LINE3DEX関数を実装する

以下の関数を使うと、2048本のLINE2D相当の処理をさせても80FPSを維持できた。 void Line2DEx(GFloat* xPosArray, GFloat* yPosArray, int num, int col) { D3DXMATRIX mat1; D3DXMATRIX matV, mat2; G3dDevice->GetTransform(D3DTS_VIEW, &matV); D3DXMatrixInverse(&mat1, NULL, &matV); D3DXMatrixScaling(&mat1, 1, 1, 1); // D3DXMatrixMultiply(&mat2,&mat1,&GMatWorld); G3dDevice->SetTransform(D3DTS_VIEW, &mat1); G3dDevice->SetRenderState(D3DRS_LIGHTING, FALSE); G3dDevice->SetRenderState(D3DRS_AMBIENT, 0xFFFFFFFF); G3dDevice->SetStreamSource(0, pPointVB, sizeof(D3DPOINTVERTEX)); G3dDevice->SetVertexShader(D3DFVF_POINTVERTEX); G3dDevice->SetTexture(0, NULL); G3dDevice->SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE); // カリングモード D3DPOINTVERTEX* p2V; HRESULT hr = pPointVB->Lock(0, sizeof(D3DPOINTVERTEX)_num, (BYTE__)&p2V, 0); if (hr != S_OK) return; float t; if (ViewType == 7) t = (float)tan(CCDZoom_M_PI / 360.0); else t = (float)tan(Zoom_M_PI / 360.0); float t2 = (t + 1) / t; for (int i = 0; i < num; i++) { p2V[i].x = (float)xPosArray[i]_t; p2V[i].y = (float)yPosArray[i]*t; p2V[i].z = (float)1; p2V[i].color = col | 0xff000000;

Rigidmain.cppの 4329行目の D3DPOOL_DEFAULT を D3DPOOL_SYSTEMMEM に置き換えたら　当環境では早くなった

Atom3735F内蔵グラのタブでLINE8千本描画時(影CCDｵﾌ) B26:0.6FPS B26@3DAnalyzer:4FPS C3(上の関数使ったやつ):25FPS あとはC側関数呼び出しのｵｰﾊﾞｰﾍｯﾄﾞが問題っぽいんでこれ以上互換性維持しての高速化は無理っぽいぽい
