示例1: ModelNode
ModelNode *Md2Importer::getModelNode() {
// retrieves the main md2 frame
Md2Frame *mainMd2Frame = this->getMainMd2Frame();
// creates a new model node
ModelNode *modelNode = new ModelNode();
// sets the model node position
modelNode->setPosition(0.0, 0.0, 0.0);
// sets the mesh list in the model node
modelNode->setMeshList(&mainMd2Frame->meshList);
// returns the model node
return modelNode;
}示例2: update
void AnimNode::update(Model *model, float lastFrame, float nextFrame, float scale) {
if (!_nodedata)
return;
ModelNode *target = model->getNode(_name);
if (!target)
return;
// Determine the corresponding keyframes
float posX, posY, posZ;
_nodedata->interpolatePosition(nextFrame, posX, posY, posZ);
float oX, oY, oZ, oA;
