Hi.
I have the following scene:
#version 3.7;
global_settings{ assumed_gamma 1.0 }
camera{
orthographic
location <0, 4, 0>
look_at 0
sky z
up 4*z
right 4*x
}
light_source{ <1, 2, 1>*100000 color srgb 1 }
plane{y, 0 pigment{ color srgb 0.75 } }
cylinder{ <0, 0, 0>, <0, 2, 0>, 0.5 pigment{ color srgb <0.4, 0.2, 0.3> } }
Let's say the z vector/axis is the north direction (the middle finger too) and
the x axis (the west and the thumb of your left hand if I'm not saying any
mistakes ?). With the above code, povray renders me a image with the cylinder
shadow on the plane that goes to the south east. But given the camera settings
and the light_source coordinates, I should have a shadow that is cast to the
south west direction. When I add the following line in the camera block:
direction -4*y
I get the wanted result. I'm sure I'm missing something but I don't know what.
I'm asking your help because I'm a little lost :-(.
Ps: from my point of view, the above camera settings (without the 'direction'
line) should make a camera without any mistaking for povray , I mean povray
shouldn't need to append default settings because it has everything it needs to
make the render ?
Thank you.
