/*
|
||||
* This example shows how to use color pick algorithm for finding node at scene.
|
||||
* Enable color pick mode of meshes and scene objects.
|
||||
* Click (left for color pick, right for geometry pick) on 3D object and see
|
||||
* in terminal time response of the found node.
|
||||
* Use key UP/DOWN for changing z coordinate of camera
|
||||
* Use key LEFT/RIGHT for scale each node
|
||||
* Use shortcut parameters of commanline: r - rows of objects, c - columns of objects, m - path for model name,
|
||||
* f - path for first texture, s - path for second texture.
|
||||
* Compile with "gcc -o evas-3d-colorpick evas-3d-colorpick.c `pkg-config --libs --cflags evas ecore ecore-evas eo eina efl`
