void *  tab,
uint32  stride,
uint32  numAttrib,
bool  allowNoCopy = false,
uint32  srcStep = (1 << 16)
)  const [virtual, inherited]
 

Fill tab with an attribute by using the given stride. It fills numAttrib attributes.

Parameters:
loc the 'located' that hold the 'located bindable' that need an attribute to be filled
startIndex usually 0, it gives the index of the first element in the located (is it multiplied by the step)
tab where the data will be written
stride the stride, in byte, between each value to write
numAttrib the number of attributes to compute
allowNoCopy data may be already present in memory, and may not need computation. When set to true, this allow no computation to be made the return parameter is then le location of the datas. this may be tab (if recomputation where needed), or another value for this to work, the stride must most of the time be sizeof(T). This is intended to be used with derivers of CPSAttribMaker that store values that do not depend on the input. The make method then just copy the data, we is sometime useless
srcStep A fixed-point 16:16 value that gives the step for the source iterator
Returns:
where the data have been copied, this is always tab, unless allowNoCopy is set to true, in which case this may be different

Implements NL3D::CPSAttribMaker< float >.
