From 5b130704cde3a82ffe63e21efb27181ea66b33de Mon Sep 17 00:00:00 2001 From: Seungho Baek Date: Mon, 4 Mar 2024 18:08:27 +0900 Subject: [PATCH] [Tizen] Add CastShadow and ReceiveShadow for Model and ModelNode - CastShadow can be used to make an object cast shadow or not. - ReceiveShadow can be used to make an object be not drawn any shadow on its surface. - Model and ModelNode have the methods. - If Model's method is called, it is inherited to its current child ModelNode. - If ModelNode's method is called, it is only affects the ModelNode itself. - The ModelNode's property changes do not affect its parent Model's property.
