/*
/*
* This example shows how to work frustum culling.
* Use keys Up/Down for moving far plane of frustum.
* Use keys Left/Right for changing camera view.
* See in terminal output value of z coordinate of far plane of frustum
* and check OBB's points inside frustum.
* @see evas_3d_node_obb_frustum_check.
* Compile with "gcc -o evas-3d-frustum evas-3d-frustum.c `pkg-config --libs --cflags evas ecore ecore-evas eo`"
* Use 'w'/'s' key to move far frustum plane from/to the camera.
* Use 't'/'g' key to move near frustum plane from/to the camera.
* Use '1'/'2' key to set camera to the first/second position.
* Use '3'/'4'/'5' key to set bounding sphere/aabb/central point mode.
* Use 'i', 'k', 'j', 'l', 'u' and 'o' keys to move mesh node in 3D.
* Use 'z', 'x', 'c', 'Z', 'X' and 'C' keys to change scaling constants of mesh.
* See in terminal output value distance to far plane of frustum and value of visibility of node
* @see evas_3d_camera_node_visible_get.
* Compile with "gcc -o evas-3d-frustum evas-3d-frustum.c `pkg-config --libs --cflags evas ecore ecore-evas eo eina` -lm"
