示例1: addWorldMaterialTemplate
//------------------------------------------------------
void MaterialService::addWorldMaterialTemplate(unsigned int idx, const Ogre::MaterialPtr& material) {
assert(!material.isNull());
mTemplateMaterials.insert(make_pair(idx, material));
TextureDimensions2D dimensions;
dimensions.first = 64;
dimensions.second = 64;
if (material->getNumTechniques() > 0) {
Pass *shadPass = material->getTechnique(0)->getPass(0);
if (shadPass->getNumTextureUnitStates() > 0) {
TextureUnitState* tus = shadPass->getTextureUnitState(0);
try {
// ensure the material is loaded before getting the dimensions
material->escalateLoading();
// This is stupid, but can happen - the getTextureDimensions seems buggy in this regard
if (tus->getNumFrames() <= 0) {
LOG_ERROR("MaterialService: Error getting texture dimensions (Mat. %s) : Zero frame count!", material->getName().c_str());
} else {
dimensions = tus->getTextureDimensions();
// register the scale
std::pair<float, float> tscale;
tscale.first = tus->getTextureUScale();
tscale.second = tus->getTextureVScale();
// register the texture scale...
setWRTextureScale(idx, tscale);
// reset the scale back, it is canceled out by the fact we UV map with different txt dimensions
