sizing objects in d3d
Author
is it possible to resize an object declared in model space? ( during gameplay )?
thanks to anyone that can help w/ some code.
I assume that scaling the matrix isn''t enough?

i tried that, and believe i did it correctly..
D3DXMatrixScaling(&someMatrix,theX,theY,theZ);
and added to one of the coordinates before...but it only moves the object. i''m assuming i''m going to have to re-initialize the vertices? that doesn''t seem logical, though...

I use this code - don''t know how fast it is (it does 2 matrix multiplies).
D3DXMATRIX MatTemp,Scalem;
D3DXMatrixIdentity(&Scalem);
D3DXMatrixScaling(&MatTemp,x,y,z);
D3DXMatrixMultiply(&Scalem, &Scalem, &MatTemp);
D3DXMatrixMultiply(&Matrix, &Scalem, &Matrix);
Just a note - if the model is not central (ie it''s origin is not 0,0,0) then your model will ''move'' when scaling.
