You may not be a computer whiz, but that doesn't mean you can't learn about and use programs like AutoCAD and Photoshop. With this step-by-step guide to the basics of design software, you'll be able to use these popular programs in no time! Once you've got the hang of it, continue on your journey by downloading other helpful tools for modeling 3D objects such as 123D Sculpt Free (for sculpting), MeshLab (for editing meshes), and SketchUp (for rendering). Don't forget to check out our book page for more book recommendations. Lighting is the most significant part of any rendering. Without realistic lighting, computer art will always look fake. You can use image-editing software to add lighting effects to your images, or you can use 3D modeling software with photorealistic built-in lighting features. When using Photoshop, it helps to know that when editing 3D models in Photoshop, you can preview how the model will look when rendered using the Ray Tracing option in the Ray Map group in the Properties menu. You can use this feature anytime you are adjusting a 3D model in Photoshop, but it's particularly helpful when making changes to a model's transparency or reflection settings. Choose a model for which you have access to the source files. This will enable you to create a high-resolution image that can be used as a screen saver or desktop background. You can obtain this type of image by creating it yourself or downloading one from an artist's website. You'll need full access to the model's source files so you can edit them freely. If you are using your own models, proceed to step 2. If not, continue here. To create screenshots for use as wallpaper or screen savers, open the model in 3D rendering software, like MeshMixer (free) or Blender (free). Set your viewport to perspective view, if it isn't already. Set up lighting using whatever method you prefer. Render your model. Save the screenshot as a JPEG by choosing File > Save As and then clicking the JPEG button in the save menu. The file should be saved into your computer's main hard drive directory. Adobe Photoshop is one of the most popular photo editing apps out there—and not just because it's free! It comes loaded with useful features for manipulating images to look more realistic. Download and install the latest version (currently Adobe Photoshop CC), and then follow these steps: When you're done, save your image as a JPEG. You can post it to social media or use it as a screensaver or wallpaper on your computer. If you want to create an animation using several images, you can follow this tutorial for more tips on creating 3D animations in Photoshop. You'll need to find high-quality images of natural landscapes—these will make your models look more realistic when you add them in later. You can find good ones by looking through stock photo websites like Shutterstock or iStock. eccc085e13
