Getting Blocks For Illustration


pro-mole

Recommended Posts

Hey guys. Anyone knows a good and/or easy way to get a render of a block to use as illustration(in my case, for my Wiki)? I'd like to have an image of each of my mod's blocks seen from a corner(you know, when the block turns into a hexagon), and only it, with a transparent background.

 

Basically, this:

Dirt.png

 

Is there some sort of app that does that?

This is how you do it, btw, the image will be upside down, but that's easy to fix in any image viewing software. Oh, and do this after the world is loaded with the sun up for the best lighting. When I did this, I bound it to a key, the screen will flash. You will probably have to adjust the rotation, this one is most probably wrong, this was off the top of my head

glPushAttrib(GL_ALL_ATTRIB_BITS);
            glPushMatrix();
            glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
            glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
            IntBuffer glFrameBuffer = BufferUtils.createByteBuffer(Minecraft.getMinecraft().displayWidth * Minecraft.getMinecraft().displayHeight * 4).asIntBuffer();
            BufferedImage bufferedImage = new BufferedImage(Minecraft.getMinecraft().displayWidth, Minecraft.getMinecraft().displayHeight, BufferedImage.TYPE_INT_ARGB);
            glEnable(GL_LIGHTING);
            glTranslatef(220f, 150f, 0f);
            glScalef(100f, 100f, 100f);
            glRotatef(90, 0.0F, 1.0F, -1.0F);
            ForgeHooksClient.bindTexture(Block.stone.getTextureFile(), 0);
            Minecraft.getMinecraft().renderGlobal.globalRenderBlocks.useInventoryTint = true;
            Minecraft.getMinecraft().renderGlobal.globalRenderBlocks.renderBlockAsItem(Block.stone, Color.WHITE.getRGB(), 1.5F);
            glPixelStorei(GL_PACK_ALIGNMENT, 1);
            glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
            glReadPixels(0, 0, Minecraft.getMinecraft().displayWidth, Minecraft.getMinecraft().displayHeight, GL12.GL_BGRA, GL12.GL_UNSIGNED_INT_8_8_8_8_REV, glFrameBuffer);
            int array[] = new int[Minecraft.getMinecraft().displayWidth * Minecraft.getMinecraft().displayHeight];
            glFrameBuffer.get(array);
            bufferedImage.setRGB(0, 0, Minecraft.getMinecraft().displayWidth, Minecraft.getMinecraft().displayHeight, array, 0, Minecraft.getMinecraft().displayWidth);
            File file = new File("C:/BlockPics");
            file.mkdirs();
            file = new File("C:/BlockPics/" + Block.stone.getBlockName() + ".png");
            try {
                file.createNewFile();
                ImageIO.write(bufferedImage, "png", file);
            } catch (IOException ex) {
                FMLLog.getLogger().log(Level.SEVERE, "Error Saving File!", ex);
            }
            glPopMatrix();
            glPopAttrib();

Well, took me long enough to actually try this and...

...yea. This didn't really work. =/ Welp, guess I can start learning some Blender. Won't do any bad, I suppose.

In case anyone's wondering, here's the result with Blender:

Yes, it's basically dirt-colored stone. :P But there we go. I'm thinking of making a tutorial for this, just gotta reorganize the steps I took from 3 different tutorials. Also, work on that other tutorial I was planning to write about extracting items with modded tools. Anyhow, thanks a bunch, y'all.
