It looks great!

I haven't made friends with the shadow maps yet

. So far I have only had problems with them.
But I think I'll learn someday.
Thank you.

For stencil shadows with "Carmack’s Reverse".
It's okay if it doesn't work, I'll do something else.

Hello.
Is it possible to increase or decrease the value in the stencil only if the pixel is not affected by the stencil function in love.graphics.stencil?

siberian

Thank you so much.
I can't believe I didn't notice that option.

I have seen this example.
I don't really need a circle with a hole in it. I ran into a problem when I was making shadows in 3d. And for that you need to draw the shadow volume twice in the stencil with different StencilAction.

Hello everyone. I used two calls love.graphics.stencil() function in my program. local function stencil_test() lg.circle('fill', cx, cy, radius) end function love.draw() local w, h = lg.getDimensions() lg.setCanvas({canvas, stencil = true}) lg.clear(0.2, 0.2, 0.2) cx, cy, radius = w/2, h/2, 200 lg.s...

There is a comment in file lighting.glsl

Code: Select all

// love2d use row major matrices by default, we have column major and need transpose it.
// 11.3 love has bug with matrix layout in shader:send().
vec4 position(mat4 transform_projection, vec4 vertex_position) {
      ...
}

What kind of bug?

Very nice!

so the main idea is to check if a dot from one of these polygon is inside the other one, is'nt it ? Sorry, it's hard for me to explain it in English. If you want to check if the two boxes intersect, then you need to check if the center of the first object is included in the polygon obtained as a Mi...
