Rendering sometimes too dark, changes with camera angle

[Reika]

When I render things with OpenGL directly, sometimes they render too dark, like my GLcolor command was set to about 70% the given values. It is a function of the camera angle and position, and if I move carefully, I can reproduce it on demand once discovering a "trigger angle". Is this related to how sometimes my TileEntities render as if they were in full blackness, often controlled by the same thing? For what it is worth, disabling GLBlend makes it ALWAYS too dark.

 

My code:

            		ModLoader.getMinecraftInstance().entityRenderer.disableLightmap(1);
            	        GL11.glPushMatrix();
            	        GL11.glTranslated(p2, p4+2, p6+1);
            	        GL11.glScalef(1.0F, -1.0F, -1.0F);
            	        GL11.glTranslatef(0.5F, 0.5F, 0.5F);
            	        GL11.glPopMatrix(); 
            	    	GL11.glDisable(GL11.GL_LIGHTING);
            	    	GL11.glEnable(GL11.GL_BLEND);
            	    	GL11.glDisable(GL11.GL_TEXTURE_2D);
            	    	GL11.glDisable(GL12.GL_RESCALE_NORMAL);
            	    	GL11.glEnable(GL11.GL_CULL_FACE);
            	    	GL11.glDisable(GL11.GL_DEPTH_TEST);
            	    	GL11.glBindTexture(GL11.GL_TEXTURE_2D, 0);
            	    	//GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);
            			GL11.glPointSize(2F);
            			GL11.glBegin(GL11.GL_POINTS);
            			double[] color = new double[3];
            			int sc = 16;
            			int a = Math.abs(i);
            			int b = Math.abs(j);
            			int c = Math.abs(k);
            			//ReikaJavaLibrary.pConsole(i+"   "+j+"   "+k);
            			color[0] = (a%sc)/(double)sc;
            			color[1] = (b%sc)/(double)sc;
            			color[2] = (c%sc)/(double)sc;
            			if (ReikaArrayHelper.sumArray(color) < 0.25) {
            				color[0] *= 4;
            				color[1] *= 4;
            				color[2] *= 4;
            			}
            			if (ReikaArrayHelper.sumArray(color) < 0.5) {
            				color[0] *= 2;
            				color[1] *= 2;
            				color[2] *= 2;
            			}
            			GL11.glColor3d(color[0], color[1], color[2]);
            			GL11.glVertex3d(p2+i, p4+j, p6+k);
            			double spread = 0*0.03125/8;
            			if (spread > 0) {
            			for (double m = -spread; m <= spread; m+= spread/2D) {
                			for (double l = -spread; l <= spread; l+= spread/2D) {
                    			for (double n = -spread; n <= spread; n+= spread/2D) {
                    				GL11.glVertex3d(p2+i+m, p4+j+l, p6+k+n);
                    			}
                			}
            			}
            			}
            			GL11.glEnd();
            			GL11.glEnable(GL11.GL_TEXTURE_2D);
            	    	        GL11.glEnable(GL11.GL_DEPTH_TEST);
            			ModLoader.getMinecraftInstance().entityRenderer.enableLightmap(1);

 

Desired Colors:

 

Dark rendering (notice the slight turn to the right):

No replies, and less than 20 views, even after 3 days? Does noone have any ideas?

[Naiten]

I hope that will help.

        float f = block.getBlockBrightness(world, i, j, k);
        tessellator.setColorOpaque_F(f, f, f);
        
        int l = world.getLightBrightnessForSkyBlocks(i, j, k, 0);
        int l1 = l % 65536;
        int l2 = l / 65536;
        OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, (float)l1, (float)l2); 

Don't forget pressing "Thank you" if it does...

Did you already try RenderHelper.disableStandardItemLighting(); before you render your stuff?

[Reika]

@Naitenne:

That code assumes I am using the Tessellator, which I am not (due to overhead reasons). I am using OpenGL directly. Also, I want full brightness all the time, not one calculated based on other lighting.

I used disableEntityLighting as the render code is found in my TileEntity render file, but disabling Item Lighting as well seems to have fixed the problem. Why would item lighting be relevant when rendering a TileEntity?

Thank you for helping me nonetheless.

Did you look what the method does? It just disables some OpenGL stuff regarding lightning. So don't get confused by that name ^^

Looking through it, it is simply 4 GL calls. Yes, that makes sense. I just wish Mojang/MCP would name methods as per their functions.

Okay, just use second part of that.

int l = world.getLightBrightnessForSkyBlocks(i, j, k, 0);
        int l1 = l % 65536;
        int l2 = l / 65536;
        OpenGlHelper.setLightmapTextureCoords(OpenGlHelper.lightmapTexUnit, (float)l1, (float)l2);  

Also, you can write Tessellator tessellator = Tessellator.instance; and still use your OGL renderer.

And as renderer updates frequently, you will have dynamic lighting. Trust me.

Again:

[*]The tessellator slows everything down when you need to render 40000 points

[*]I want no lighting at all - permanent full brightness no matter what

[*]My problem is not lighting that is controlled by the environment, but that which seems controlled by camera relative angle and position alone

Also, as above, SAP's solution seems to be working.

Okay, you should have said you don't need lighting at all...

That much becomes clear from my code...did you not see disableLightMap()?
