From fe8bf2fa556a56c4d541a334a329467120c11a28 Mon Sep 17 00:00:00 2001 From: raysan5 Date: Fri, 25 Sep 2020 18:14:46 +0200 Subject: [PATCH] REVIEWED: GenTextureCubemap(), use rlgl functionality only Function has been reviewed to avoid any direct OpenGL call and use rlgl functionality, also, GenDrawCube() has been replaced by the internal batch system with DrawCube(). WARNING: rlEnableTexture() call must be issued after enabling the current framebuffer when using batch mechanism because it includes a set of security checks to avoid batch overflow and push/pop matrix operations. --- src/rlgl.h | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/src/rlgl.h b/src/rlgl.h index 2710beb84..0ecf1cb52 100644 --- a/src/rlgl.h +++ b/src/rlgl.h @@ -3327,8 +3327,8 @@ TextureCubemap GenTextureCubemap(Shader shader, Texture2D panorama, int size, in }; rlEnableShader(shader.id); - glActiveTexture(GL_TEXTURE0); - glBindTexture(GL_TEXTURE_2D, panorama.id); + //glActiveTexture(GL_TEXTURE0); + //glBindTexture(GL_TEXTURE_2D, panorama.id); rlViewport(0, 0, size, size); // Set viewport to current fbo dimensions @@ -3338,8 +3338,14 @@ TextureCubemap GenTextureCubemap(Shader shader, Texture2D panorama, int size, in rlFramebufferAttach(fbo, cubemap.id, RL_ATTACHMENT_COLOR_CHANNEL0, RL_ATTACHMENT_CUBEMAP_POSITIVE_X + i); rlEnableFramebuffer(fbo); + rlEnableTexture(panorama.id); // WARNING: It must be called after enabling current framebuffer if using internal batch system! + rlClearScreenBuffers(); - GenDrawCube(); + //GenDrawCube(); + + // Using internal batch system instead of raw OpenGL cube creating+drawing + DrawCubeV(Vector3Zero(), Vector3One(), WHITE); + DrawRenderBatch(RLGL.currentBatch); } //------------------------------------------------------------------------------------------
