Hello, i am newbie here..
Currently i am developing 3D environment + 2D map for my final project (Opengl,C++)
My problem is how to draw the "Circle Shape" Map to the 3D environment screen?
It like a GTA interactive map..
Any idea?
Circle 2D Map
Re: Circle 2D Map
GTA3 does it by a circle texture with an alpha with a GE128 blend and a depthwrite, and many small textures of the map in little pieces (since PS2 cache sucks)
then it reads the depth of that circle texture to trim it to that circle
A second alpha-blended circle is applied on top to soften the transition with a black circle border.
then it reads the depth of that circle texture to trim it to that circle
A second alpha-blended circle is applied on top to soften the transition with a black circle border.
i should not be here
