If you render fewer triangles, curved models can look “blocky”. The sphere edges look curved because of the number of triangles being rendered - the GPU is only rendering straight lines here. This tells the GPU to render lines instead of solid triangles.
CHEETAH3D 2.6 CODE
To render in wireframe, add the following line of code just before the draw call: tTriangleFillMode(.lines) Rendering a model in wireframe allows you to see the edges of each individual triangle. Undo that last change and revert back to rendering solid triangles.
You can really see the 3D nature of the sphere now! The vertices are evenly spaced horizontally, but because you’re viewing on a two dimensional screen, the points at the edges of the sphere appear closer to each other than the points in the middle. Run the playground and you’ll see this result: point: renderEncoder.drawIndexedPrimitives(type. Near the end of the playground, change the draw call from using type. To view the sphere as vertices instead, switch the render mode from triangles to points. Examine the rendered sphere in the playground’s live view at the moment, the sphere renders as a solid red shape. This contains the code from Chapter 1, “Hello, Metal!”. If you don’t see these things, you may need to show the Project navigator using the icon at the top-right.įrom the Project navigator, select Render and Export 3D Model. This playground contains two pages, Render and Export 3D Model and Import Train. Open the starter playground for this chapter. Each vertex refers to a point in 3D space, made up of x, y and z values.Īs you saw in the previous chapter, you send these vertex points to the GPU for rendering. What are 3D models?ģD Models are made up of vertices.
CHEETAH3D 2.6 HOW TO
You’ll learn how to create them, what they’re made of and how to render them with different colors and styles. In this chapter, you’ll examine 3D models. Nonetheless, the principle of rendering 3D models is the same. What you see on the screen are 3D models rendered with custom renderers, much like the one you wrote in the previous chapter, only more advanced.
What makes a good game even better? Gorgeous graphics! Creating amazing graphics like those in The Witcher 3, Doom and Uncharted 4, requires a team of programmers and 3D artists working closely together.

It encourages clean separation of content, graphic design, and program code. It provides a simple, yet powerful, caching mechanism that can dramatically improve the performance of a dynamic website. Cheetah templates can be subclasses of any Python class and vice-versa. One template can subclass another and selectively reimplement sections of it. Meanwhile, it provides a way for administrators to selectively restrict access to Python when needed.Ĭheetah makes code reuse easy by providing an object-oriented interface to templates that is accessible from Python code or other Cheetah templates.
CHEETAH3D 2.6 FULL
It gives template authors full access to any Python data structure, module, function, object, or method in their templates. It blends the power and flexibility of Python with a simple template language that non-programmers can understand. It can output/generate any text-based format.Ĭheetah compiles templates into optimized, yet readable, Python code. It is fully documented and is supported by an active user community. Cheetah is supported by every major Python web framework.
