void Ogre::MeshManager::_initialise | ( | ) |
Initialises the manager, only to be called by OGRE internally.

const String & | group, | ||

const String & | groupName, | ||
v1::Mesh * | mesh, | ||
bool | halfPos, | ||
bool | halfTexCoords, | ||
bool | qTangents, | ||
bool | halfPose = true ) |
Imports a v1 mesh to new mesh, with optional optimization conversions.
name | The name to give the new mesh |
groupName | The name of the resource group to assign the mesh to |
mesh | The source v1 mesh to convert from. You can unload but should not delete this pointer if you want to be able to reload the converted mesh. |
halfPos | True if you want to convert the position data to VET_HALF4 format. Recommended on desktop to reduce memory and bandwidth requirements. Rarely the extra precision is needed. Unfortuntately on mobile, not all ES2 devices support VET_HALF4. |
halfTexCoords | True if you want to convert the position data to VET_HALF2 or VET_HALF4 format. Same recommendations as halfPos. |
qTangents | True if you want to generate tangent and reflection information (modifying the original v1 mesh) and convert this data to a QTangent, requiring VET_SHORT4_SNORM (8 bytes vs 28 bytes to store normals, tangents and reflection). Needs much less space, trading for more ALU ops in the vertex shader for decoding the QTangent. Highly recommended on both desktop and mobile if you need tangents (i.e. normal mapping). |
halfPose | True if you want the pose buffer to have pixel format PF_FLOAT16_RGBA which uses significantly less memory. Otherwise it is created with pixel format PF_FLOAT32_RGBA. Rarely the extra precision is needed. |
MeshPtr Ogre::MeshManager::createManual | ( | const String & | name, |
const String & | groupName, | ||
ManualResourceLoader * | loader = 0 ) |
Creates a new Mesh specifically for manual definition rather than loading from an object file.
name | The name to give the new mesh |
groupName | The name of the resource group to assign the mesh to |
loader | ManualResourceLoader which will be called to load this mesh when the time comes. It is recommended that you populate this field in order that the mesh can be rebuilt should the need arise |
