I would like to display the total number of poly's currently in the viewport and I would like to display the total number of poly's in the scene. I've been looking through the docs and cannot find any obvious way to do this. Can anyone point me in the right direction?
Thanks.
There is no obvious way. You need to maintain your own count. Everywhere you render something add the # triangles to a counter. Clear it every frame.
in 3d this means getting ModelMeshPart.PrimitiveCount - or if you are using vertex buffers count them yourself.
in 2d assume each sprite.Draw is 2 triangles
Point it at your compiled executable, select the "Statistics for each
frame" option, click the "HUD" checkbox, then run your game. This will
overlay draw call statistics on the game screen. You can press F12 to
toggle which data is displayed. This mode doesn't actually seem to show
the total triangle count, but it will tell you how many draw calls and
renderstate changes are happening, which is usually actually more
important for affecting the overall performance.
If you select "A single frame capture of Direct3D whenever F12 is
pressed", then you can run your game to the point you are interested in
measuring, press F12, then when you quit the game, you'll get a really
detailed view of exactly what calls it issued during the frame you
captured. Again I can't see any really easy way of extracting the total
triangle count, but you could export all this data to a
comma-separated-value format using the File menu (making sure you
include Function Call data), then write a little program to scan this
file and add up the triangle count information.
Thanks for the tip Shawn, great tool. The hud is nice too. Help is non-existant for this tool. Where can I find info on what these call abbreviations stand for?
edit: never mind, I should have read more carefully
