Description
|
|
===========
|
|
The Pick sample shows how to implement "picking" which is finding which
|
|
triangle in a mesh is intersected by a ray. In this case, the ray comes
|
|
from mouse coordinates.

User's Guide
|
|
============
|
|
The following keys are implemented. The dropdown menus can be used for the
|
|
same controls.
|
|
<Enter> Starts and stops the scene
|
|
<Space> Advances the scene by a small increment
|
|
<F1> Shows help or available commands.
|
|
<F2> Prompts user to select a new rendering device or display mode
|
|
<Alt+Enter> Toggles between fullscreen and windowed modes
|
|
<Esc> Exits the app.
|
|
|
|
Use the mouse to "pick" any spot in the mesh to see that triangle.

Programming Notes
|
|
=================
|
|
When the user clicks the mouse, the code reads the screen coordinates of the
|
|
cursor. These coordinates are converted, via the projection and view matrices,
|
|
into a ray which goes from the eye point through the point clicked on the screen
|
|
and into the scene. This ray is passed to IntersectTriangle along with each
|
|
triangle of the loaded model to determine which triangles, if any, are
|
|
intersected by the ray. The texture coordinates of the intersected triangle
|
|
is also determined.

This sample makes use of common DirectX code (consisting of helper functions,
|
|
etc.) that is shared with other samples on the DirectX SDK. All common
|
|
headers and source code can be found in the following directory:
