1. ## Need Buffer Clarification

Thank you very much.. That pretty well cleared it up for me..

3. ## Size limit of world and view space

Thank you for the reply.. I see what you are talking about the possible world transfomation problem. perhaps the scaling method might be better..
4. ## Size limit of world and view space

Hi, Im new to directx and have a question. I wanted to start out simple so I decided to build a solar system and have a ship travel to and from.. The ship would have the view point of the camera. The distances are in millions and billions of units (Km) so I wanted to know if the world and view space (transfomations) have any limit to size? This would make my life easier.. Or would the prefered method be to keep all the planets closer on the edge of a large playfield and use scaling to give the perception of getting closer or farthur away from a planet. ?
5. ## Directx 10 3D Objects to screen coords.

Thank you very much.. This will definitly get me in the right direction..
6. ## Directx 10 3D Objects to screen coords.

Hello, I would like to program to use the cursor to click on a 3D object and know that It clicked on it..Im using DirectX 10.. Is there a DX function to do this ? I have not had much luck searching for this on the web.. It might be I cant describe what Im trying ot do in the search. I can find where my cursor is no problem as I use my own class with a quad for my cursor.. just need to figure out 3D objects to screen coord I guess. A nudge in the right direction will be greatly appeciated.. Im using C++ Thanks
7. ## compute 3D point on a vector

Thank you Cornstalks and Haegarr I was not sure how to create a velocity vector that would not wander off from the vector between A and B.This information helped a lot..thanks for helping me out.
8. ## compute 3D point on a vector

Hi, I would like to know how do to the following..I have a point in 3D space A(x,y,z) and another point B(x,y,z) If I travel from point A towards point B at a set velocity (meters per second) I would like to calculate at any given time the point position on the vector between A and B.. C(x,y,z) I already know how to calculate the distance between A and B so I have that and I know the speed.. I probably could find it with google but I dont really know how to describe it for a search.. so far I have not had any luck finding it..Thanks.
9. ## Vertex Buffer Limit

Is there a limit on the number of vertex buffers I can create and use ?. I have created a Class that generates a simple quad. The Class has its own vertex buffer and function to render the quad. I use several of these in my program and call each one from the main loop for rendering..So far I see no problems.. It works fine, no memory leaks or exceptions..But before I get too far along I wanted to be sure if there was a limit ..And if I should use managed memory pool or default memory pool when creating a lot of vertex buffers.. Im using directx 9. thanx in advance.
