Also, if you search the archives Yahn posted code for mouse picking objects on the HUD and finding corresponding world coordinates for the objects being picked. -----Original Message----- From: [EMAIL PROTECTED] Subject: [hlcoders] [hlcoders]Unproject 2D to world 3D / mouse coordinates to world Hi I have been looking into converting 2D screen coordinates into 3D World coordinates. I have using a method based on spherical and cylindrical coordinates. Is there a function like Unproject I could use? Or do I need to use a method based on sweeping a trace line around the world And using Screentransform function? No virus found in this outgoing message. Checked by AVG Free Edition.
