Step one - Go back to set-up and create the two spheres again. It appears that the other geometry has been removed and has only left the protruding surface in the boolean sphere. Actually, the geometry hasn't been deleted. Its vertice and transformation information is still there. To access it Step four - There will be two groups: pshpere1, pshpere2, and the outputted geometry.
Maximize the groups so you can see inside of them. Each one has a transform node. Step five - Select the group pshepre2 and you will find that, when using the move tool, you can move the sphere's geometry around, therefore watching the boolean in real time. Here's how a boolean works: It takes both geometry's shape nodes, connects their outputs to a boolean node, then the boolean node, based on the outputted information from the geometry shape node, generates a new mesh.
As you can see, the " out mesh " and the " worldmatrix " of both sphere's shape nodes have been connected to a boolean node and the boolean node outputs the new geometry. As mentioned before, booleans do have drawbacks. So the rule of thumb is if you need to smooth the surface later, example: organic modeling - people - animals, you probably don't want to use boolean.
If it's a surface like a monitor, computer or keyboard, booleans are great. Booleans and shaders When you boolean an object, shader information is also booleaned.
Step one - Download example file shaders. Step two - The red sphere has been assigned a blinn with its color set to red. The blue sphere has been assigned to a lambert with its color set to blue. As you can see, the shaders are also boolean, so all the faces that the red sphere intersected are red, and the rest are blue. Boolean is probably the fidgetiest function in Maya. This next section covers some common issues. One of the surface's normals is probably facing backwards.
This will show the normals as lines coming off the vertices. If you don't see any reversed normals, select the other object and reverse its normals, and that should fix it.
Fix - Select both objects and group them. Scale the group until it's noticeably larger than the grid. If you want to test this out for yourself, download badgeo. Example: you can't boolean a polygon with a NURB. Set-up To follow this tutorial it's best if you have a basic knowledge of Maya. What Is A Boonlean Booleans in Maya let you take an object, subtract, add or intersect its geometry onto another object merging. Anatomy of a Boolean If you're a beginner and don't particularly care about this, you can skip this section.
After performing a boolean operation, the original objects cannot be selected in the scene. When construction history is enabled, you can select the objects in the Channel Box , Hypergraph , Attribute Editor , or Outliner. Any changes you make to the original objects are automatically applied to the new shape. See Edit the original objects after a boolean operation.
See Legacy boolean algorithm. Boolean operations rely on the intersection, the shared volume of the two meshes, to determine the boolean result.
