ogre_StaticGeometry

StaticGeometry添加的实体要用索引形式的三角形来构建。否则程序出错。

ManualObject* manual = mSceneMgr->createManualObject("grass");
        manual->begin("Examples/GrassBlades", RenderOperation::OT_TRIANGLE_LIST);

        //6
        manual->position(5.0, 0.0, 0.0);
        manual->textureCoord(1, 1);
        manual->position(-5.0, 10.0, 0.0);
        manual->textureCoord(0, 0);
        manual->position(-5.0, 0.0, 0.0);
        manual->textureCoord(0, 1);
        manual->index(0);
        manual->index(1);
        manual->index(2);


        //8
        manual->end();

        manual->convertToMesh("bladesGrass");

        StaticGeometry* field = mSceneMgr->createStaticGeometry("fieldGrass");

        for (int i= 0; i < 50; ++i)
        {
            for (int j = 0; j < 50; ++j)
            {
                Entity* ent = mSceneMgr->createEntity("bladesGrass");
                field->addEntity(ent, Vector3(i*3, -10, j*3));
            }
        }

        field->build();
