Hi
Thank you for your answer.
I have tried to create a simple example to have a reflection.
It work, but I don't know if there is a way to get an orthographic view with the camera.

I'm sorry, I don't know how to construct an orthographic matrix in the shader ^^
What is myOrthoMat ?
Here is the code for a reflection/shadowmap, If the camera should be orthographic, I think it could work ^^ :
// Project: 3D_reflection
// For reflection and shadow
// Created: 2015-12-04
SetWindowTitle( "3D_reflection" )
SetWindowSize( 1024, 768, 0 )
DW = 1024
DH = 768
SetVirtualResolution( 1024, 768 )
SetOrientationAllowed( 1, 1, 1, 1 )
SetClearColor(0.64*255,0.84*255,255)
// position and orientate camera
SetCameraPosition(1,0,20,-50)
SetCameraLookAt(1,0,0,0,0)
// Two sphere to reflect
CreateObjectSphere(1,5,15,15)
SetObjectPosition(1,5,5,5)
CreateObjectSphere(2,5,15,15)
SetObjectPosition(2,-5,5,5)
CreateObjectBox(4,5,30,5)
SetObjectPosition(4,-18,0,12)
// for the reflection
CreateRenderImage(1,512,512,0,0)

oldry#=GetCameraAngleY(1) //-45.0
oldrz#=GetCameraAngleZ(1)
// render to image, for reflection // should be the same for shadow
SetRenderToImage(1,-1)
SetCameraFov(1,110)
