BLENDER VIDEO EDITING CHANGE FRAME RATE HOW TO
BLENDER VIDEO EDITING CHANGE FRAME RATE SOFTWARE

We are going to use Blender to create our scene, bake it, and export it.

Import everything in Three.js and apply the texture on the mesh.Īs a bonus, we will also add some details in Three.js to give more life to the scene like a cool portal effect with fireflies floating around.

But, we can have multiple textures if there are a lot of objects and we want better quality. If we do this, we are going to have just one big texture.

Export both the scene and the texture(s).

Optimize all the objects because we need clean geometries and only the surfaces we can see.

To create that baked scene, we need to go through multiple steps: Keep in mind that you can still mix baked and non-baked materials but it's hard to keep a homogeneous result.

We have to do it in the 3D software and re-bake everything.Ĭhoosing to use baking or not is up to you and the project. We can't move the lights, and we can't change their intensity or color in real time. This is bad for loading but it can also result in a short freeze at the beginning of the experience because we need to load those textures into the GPU.

We have to load the textures and if you have a complex scene with a lot of objects, you're going to need a lot of textures.

We have to bake everything in the 3D software and it's a long process.

And when we move around the scene, the performance will be great because all we did was to display a texture on a geometry. This way, we will see the Ray Tracing renders directly on the Meshes, and it looks awesome. It's just the texture you see in the above example being placed on the geometries. The idea of baking is that we save those Ray Tracing renders into textures that we then use in WebGL instead of using the classic render techniques provided by Three.js. For this reason, rendering in WebGL uses cheaper techniques that don't look as good but at least keep a decent frame rate. We don't have the luxury to spend minutes on just one render. When we are doing renders with WebGL, we need to do it as fast as possible in order to get a good frame rate. This process results in a beautiful realistic render, but doing one render can take many minutes, even hours.

In the same way, you'll see that the red object looks brighter when the surface is close to the white object. As an example, if you place a red object close to a white object, you'll see the white object being tinted with red because rays are bouncing from the red surface to the white surface. The goal is to simulate real-life lighting and enable visual effects like indirect lighting and soft shadows. All of the information collected by these collisions is then computed to define the final color of that pixel. And it goes on and on like this multiple times.

Then, for each of these collisions, more rays are being cast as they bounce off other objects. Next, they test the direction of each light in the scene to see which part of the geometry is illuminated as well as to test whether the directions of the light bouncing off the geometry are colliding with other objects in the scene. These rays start with the geometry we are rendering. Ray Tracing consists of casting multiple rays toward each pixel of the render. This is because of the technique used while making the render. When you do a render in a 3D software like Blender, it usually looks better than the model you import into Three.js, no matter how hard you try to get the exact same lighting and colors. Or anything else!Īnd, to make our scene look its best, we are going to use a technique called baking. When you are done, you will be able to use what you've learned to create rooms like the ones on Three.js Journey. We are going to create a small landscape with a path leading to a magical portal with some objects along the way like fences, trees, rocks.
