Hi again! As I said in my previous reply, I tried to remove the "extern", and use instead a const array (so no need to use any parameter slot at all). Well, I was very surprised to notice a dramatic loss of framerate. The result was about 2 FPS; Adding a "const" seems to boost it...

Well, I managed to make it work :) I am not sure why you feel using a texture is overkill. When you pass a texture you a) Give the shader something it's made to work with and work with fast b) Only use up one shader parameter slot As I said, this is a totally new world for me; "texture" so...

I think that in this case you don't need to send anything... (I assume that 600 is screen height) myShader = love.graphics.newShader[[ vec4 effect( vec4 color, Image texture, vec2 texture_coords, vec2 screen_coords ){ //note that GLSL counts y coordinates from the bottom of the screen so you may wa...

If you're passing 600 values to the shader you're probably doing something wrong already, but nevertheless this could work: myShader:send("field",unpack(field)); Thanks S0lll0s! The idea is to pass the 600 values only once. I'm new to shaders, but I've seen peoples passing whole texture i...

Hi, First of all, I'm new to Löve, to lua and to glsl shaders, so I apologize in advance if I ask something stupid :). I'm trying to achieve a simple starfield effect, and I think it should be interesting to use pixel shaders for this. I made some tests and I'm getting there, however I do have an is...
