I probably missed something. Also there's some hackery when loading 3D models, which are still assumed to be in metres. --- gfx/gl/shaders/spotLight.vs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gfx/gl/shaders/spotLight.vs') diff --git a/gfx/gl/shaders/spotLight.vs b/gfx/gl/shaders/spotLight.vs index e61b641..08197a4 100644 --- a/gfx/gl/shaders/spotLight.vs +++ b/gfx/gl/shaders/spotLight.vs @@ -18,7 +18,7 @@ main() { position = v_position; direction = normalize(v_direction); - size = (8 * sqrt(max(max(colour.r, colour.g), colour.b))) / sqrt(kq); + size = (8000 * sqrt(max(max(colour.r, colour.g), colour.b))) / sqrt(kq); cosarc = cos(arc / 2); gl_Position = vec4(position - viewPoint, 0); } -- cgit v1.2.3 From 4e6f8db35ddc8fd3f310bb5616d257b5f9996d94 Mon Sep 17 00:00:00 2001 From: Dan Goodliffe Date: Sun, 3 Dec 2023 12:37:46 +0000 Subject: Shader viewPoint now an integer --- gfx/gl/shaders/spotLight.vs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gfx/gl/shaders/spotLight.vs') diff --git a/gfx/gl/shaders/spotLight.vs b/gfx/gl/shaders/spotLight.vs index 08197a4..ac1d1db 100644 --- a/gfx/gl/shaders/spotLight.vs +++ b/gfx/gl/shaders/spotLight.vs @@ -6,7 +6,7 @@ uniform vec3 v_direction; uniform vec3 colour; uniform float kq; uniform float arc; -uniform vec3 viewPoint; +uniform ivec3 viewPoint; out vec3 position; out vec3 direction; -- cgit v1.2.3
