Embodiments relate to generating image frames including a motion of a character with one or more stretchable body parts by either performing only blending of prestored animation clips or performing both the blending of prestored animation clips and performing inverse kinematics operations where one or more bones in the body parts are stretched or contracted. Choosing whether to perform blending or the inverse kinematics depends on whether predetermined conditions are satisfied or not. Prestored animation clips to be blended may be determined according to the speed of the character when performing the jumping motion. When performing the inverse kinematics, physical properties of the character are simulated to determine the trajectory of the character during the jumping.

Gap jumping simulation of stretchable character in computer game

Embodiments relate to generating a character with a stretchable body part in a computer game. A pose of a body part of the character is received. The body part includes at least one base joint, bones connected via the at least one base joint, and an end effector coupled to one of the bones. An end effector position is received. The end effector position is where an end effector of the body part is to be placed in an updated pose. Inverse kinematics operations are performed to determine the updated pose of the body part by at least changing a length of one of the bones to place the end effector at the end effector position responsive to receiving the pose of the body part and the end effector position.
