Tutorial on Drawing 3D Shapes...SceneAsset* scene = proxy.getSceneAsset("lightshow2_eksempelscene.MBA");Program* program = proxy.getProgramAsset("default.vert;default.frag")->getProgram();context->setProgram(program);3. Example 4-54 shows the camera and lighting setup:Example 4-54 Set the camera and light values...//int numCams = scene->getAssetCount(Asset::TYPE_CAMERA);int currentCam = 0;float camFov = 270.0f;float camAspect = 4.0f/3.0f;float time = timer->getTime();vec3 lightPos(0.0f, 0.0f, 0.0f);vec3 camTarget(0.0f, 0.0f, 0.0f);vec3 camPos(0.0f, 0.0f, 0.0f);...glEnable(GL_CULL_FACE);glCullFace(GL_BACK);glEnable(GL_DEPTH_TEST);4. Example 4-55 shows the part of the draw loop that manages the camera:Example 4-55 Getting the camera asset...do{#if FIXED_FRAMERATE == 1time += TIME_INCREMENT;#elsetime = timer->getTime();#endif::printf("%f\n", time);glClearColor(0.0f, 0.0f, 0.0f, 1.0f);glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT);// Get camera assetCameraAsset* cam = (CameraAsset*)scene->getAsset(Asset::TYPE_CAMERA, currentCam);if (cam){// Find nodes in camera:Array nodes;scene->findAssetNodes(cam, scene->getTree(0), nodes);// Set camera and target node:NodeAsset* camNode = nodes[0]->data;NodeAsset* targetNode = cam->getTargetNode();// Set camera positionif(camNode)camPos = camNode->getAbsolutePosition();// Set target node positionARM DUI 0527A-02a Copyright © 2010 ARM.
