I have to write a building illumination simulation : So I've got a building, and I must write an application which lets the user position lights (ie, floodlights...) around it to visualize the result. It's very important for the user to test different light intensities. Here's my problem : I'm not an opengl guru, and I don't know how you specify a light's intensity in opengl : you specify some parameters like colors, but I haven't seen anything about light intensity.
Please, can you help me ? Is there any way to specify a light's intensity ? Or, do you know any way of working around this problem ?
Any help would be highly appreciated !
