* 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
