DrTAD Blender Tutorial Animation Basics - Morphing 2 objects with Shrinkwrap Modifier & Shape Keys
0 likes466 views
The document is a tutorial on using Blender software to animate the morphing of two objects using the shrinkwrap modifier and shape keys. It explains the functionalities of the shrinkwrap modifier, which allows an object to conform to the surface of another, as well as the use of shape keys to animate deformations in 3D objects. The tutorial outlines step-by-step processes alongside visual aids to illustrate the creation of morphing animations from a cube to a sphere.

- 2. 2018 DrTAD 2 About Blender software Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. ●https://www.blender.org/ ●Modern accessible application of the system Blender in 3D design practice. https://www.researchgate.net/publication/312033613_Modern_accessibl e_application_of_the_system_Blender_in_3D_design_practice
- 3. 2018 DrTAD 3 Blender Animation - Shrinkwrap Modifier ●The Shrinkwrap Modifier allows the object to "shrink" to the surface of another object. It moves each vertex of the object being modified to the closest position on the given mesh (using one of the three available methods). It can be applied to meshes, lattices, curves, surfaces and texts. ●https://docs.blender.org/manual/en/dev/modeling/modifiers/deform/shrinkwrap.html? highlight=shrinkwrap
- 4. 2018 DrTAD 4 Blender Animation - Shrinkwrap Modifier - Options ●Target. Shrink target, the mesh to shrink to/wrap around. ●Offset. The distance that must be kept from the calculated target position, in Blender Units. ●Vertex Group. The vertex group to control whether and how much each vertex is displaced to its target position. If a vertex is not a member of this group, it is not displaced (same as weight 0). ●Mode. This selector specifies the method to be used to determine the nearest point on the target’s surface for each vertex of the modified object. Some options will add some extra, specific controls to the panel. ●Nearest Surface Point. This will select the nearest point over the surface of the shrink target. It adds the extra option Above surface, which always keep the computed vertices above their “floor faces”. This is only meaningful when Offset is not null. https://docs.blender.org/manual/en/dev/modeling/modifiers/deform/shrinkwrap.html? highlight=shrinkwrap
- 5. 2018 DrTAD 5 Blender Animation - Shrinkwrap Modifier – Mode ProjectionThis will project vertices along a chosen axis until they touch the shrink target. Vertices that never touch the shrink target are left in their original position. ●Subdivision Surface Levels. This applies a (temporary) Catmull-Clark subdivision to the modified object, before computing the wrap when using Projection mode. ●Limit. This is a distance limit between original vertex and surface. If the distance is larger than this limit vertex would not be projected onto the surface, ●Axis. Along which local axis of the modified object the projection is done. These options can be combined with each other, yielding a “median axis” of projection. X, Y, Z. ●Direction. This allows you to select the allowed direction(s) of the shrink along the selected axis. With more than one Shrinkwrap Modifier, negative and positive axes can be combined. Negative, Positive. ●Cull Faces. This radio button allows you to prevent any projection over the “front side” (respectively the “back side”) of the target’s faces. The “side” of a face is determined by its normal (front being the side “from where” the normal “originates”). ●Auxiliary Target. An additional object to project over. https://docs.blender.org/manual/en/dev/modeling/modifiers/deform/shrinkwrap.html?highlight=shrinkwrap
- 6. 2018 DrTAD 6 Blender Animation - Shrinkwrap Modifier – Mode Nearest Vertex This will snap vertices to the nearest vertex of the shrink target. It adds no extra options. ●https://docs.blender.org/manual/en/dev/modeling/modifiers/deform/shrinkwrap.html? highlight=shrinkwrap
- 7. 2018 DrTAD 7 Blender Animation - Shape Keys » Introduction Shape Keys are used to animate deform objects into new shapes. They can be applied on objects with vertices like Mesh, Curve, Surface, Lattice. There are two types of Shape Keys: ●Relative. Which are relative to the Basis or selected shape key. They are mainly used as, for limb joints, muscles, or Facial Animation. ●Absolute. Which are relative to the previous and next shape key. They are mainly used to deform the objects into different shapes over time. The shape key data, the deformation of the object’s vertices, is usually modified in the 3D View by selecting a shape key, then moving the object vertices to a new position. ●https://docs.blender.org/manual/en/dev/animation/shape_keys/introduction.html
- 8. 2018 DrTAD 8 Blender Animation - Shape Keys Panel – Absolute SK Absolute shape keys deform from the previous and to the next shape key. They are mainly used to deform the object into different shapes over time. ●Reset Timing (clock icon). Reset the timing for absolute shape keys. ●Interpolation. This controls the interpolation between shape keys. Linear, Cardinal, Catmull-Rom, B- Spline ●The red line represents interpolated values between keys (black dots). ●Evaluation Time. This is used to control the shape key influence. https://docs.blender.org/manual/en/dev/animation/shape_keys/shape_keys_panel.htmll

In Object Mode, add a new shape keys via the Shape Key panel with the + button. 2. “Basis” is the rest shape. “Key 1”, “Key 2”, etc. will be the new shapes. 3. Switch to Edit Mode, select “Key 1” in the Shape Key panel. 4. Deform mesh as you want (do not remove or add vertices). 5. Select “Key 2”, the mesh will be changed to the rest shape. 6. Transform “Key 2” and keep going for other shape keys. 7. Switch back to Object Mode. 8. Set the Value for “Key 1”, “Key 2”, etc. to see the transformation between the shape keys. ● In the figure below, from left to right shows: “Basis”, “Key 1”, “Key 2” and mix (“Key 1” 1.0 and “Key 2” 0.8) shape keys in Object Mode. ●https://docs.blender.org/manual/en/dev/animation/shape_keys/workflow.html#relative-shape-keys ●https://docs.blender.org/manual/en/dev/animation/shape_keys/shape_keys_panel.html#settings
