View Matrix from location / rotation details

kieren_j · 2000-03-26T16:25:36

Hi. Thanks for the help with the normal calculations, I wrote a function that calculates them Anyway, I''d like to know if you can help me; I want to be able to create a view matrix from these details: D3DVECTOR camera_location; // pos. in 3d space D3DVECTOR camera_rotation; // rotation angles in radians Does anybody know how it''s done (do you have any code)? All the examples in the D3DIM SDK use D3DUtil_SetViewMatrix to set up view matrices. However, this requires a "look at" point - which I don''t know how to calculate. So what sort of a matrix would I need to form? Are there functions already designed for this? I''d also like to be able to calculate a "forward direction" vector, so that I can move the camera forward by scaling it by a movement value. ! Thanks !

? won''t read .X files?

Of course not, you would have to write a reader for that anyways. Plus, I wouldn''t use the .X file format, since it is majorly bloated.

Try ASC and/or 3DS files. Matter of fact didn''t someone just release the source for an ASC reader, on the front news page of gamedev
