In the process of artistic creation or project research, motion capture technologies for human bodies and rigid bodies have become relatively mature. However, capturing the movements of quadruped animals and complex props is often regarded as a "daunting challenge". Unlike the relatively regular skeletal structure and cooperativeness of the human body, quadruped animals have skeletal architectures that differ significantly from those of humans. Small animals like cats are not only agile and flexible in their movements but also have unpredictable obedience. As for complex props, issues such as multiple moving parts, intricate shapes and structures, and multiple contact points with motion capture actors often lead to problems during motion capture, including lost tracking points, model penetration, and unsmooth capture processes.

Against this backdrop, traditional motion capture technologies often require extensive manual correction, limiting both efficiency and realism. Aiming to address these industry pain points, CHINGMU's newly upgraded CMAvatar 3.0 brings creators a brand-new high-efficiency motion capture experience. Following the Kinetiq AI solver and optical finger tracking technology, this article will continue to reveal more possible scene applications of CMAvatar 3.0.

Quadruped Motion Capture: The Leap from Simulation to Realism

In the past, the industry often resorted to "human-substituted" solutions for capturing quadruped movements, resulting in stiff animations lacking the unique agility and rhythm of real creatures. CMAvatar 3.0 breaks through this limitation by enabling direct capture of authentic animal dynamics. By attaching marker points to an animal’s fur or a specialized coat, and combining high-precision motion capture cameras with intelligent algorithms, the system accurately tracks the movement trajectory of every joint. For example, when a cat jumps, the curling of its paw pads and the undulation of its torso can be 1:1 reproduced through precise marker placement and intelligent skeletal matching technology. This ensures fluid, natural movements, infusing film and animation production with genuine biological realism.

Rigid Body & Complex Prop Capture: Precise Matching and Decoding Smooth Motion Data Chains

For general rigid body capture, motion data such as the 3D spatial position and movement trajectory of the rigid body can be obtained by capturing data from reflective marker points on the object.

However, capturing complex props still poses significant technical challenges in the industry. Take a bicycle as an example: beyond the occlusion caused by interactions between the bike and the motion capture actor’s body, its capture difficulties also stem from its unique shape, multiple moving parts, and the need for precise coordination between independently dynamic components (e.g., high-speed rotating wheels that must maintain accurate alignment with the frame).

CHINGMU Visual tackles these challenges through multi-dimensional technical collaboration:

Leveraging CMAvatar 3.0’s customizable marker placement function, markers are strategically positioned based on the bicycle’s performance style and motion patterns.

After setting up a custom skeleton template in the system, intelligent data algorithms ensure precise matching between the bicycle and its digital model, while real-time calibration of occluded areas guarantees seamless integration of wheel rotation trajectories with frame movements.

This approach breaks through technical bottlenecks, enabling smooth, interference-free motion data capture for complex props with multiple interactive components. It ensures that every detail—from the rotation of wheels to the subtle shifts in the actor’s grip—translates into accurate, coherent animation data, significantly improving the efficiency and realism of prop-driven scenes in film, gaming, and virtual production.

From Industry Breakthrough to Ecosystem Co-Construction: CHINGMU Visual CMAvatar 3.0 Captures Every Frame of Brilliance

As a leading domestic provider in optical motion capture, CHINGMU Visual has always believed that the value of technology lies not in showmanship, but in empowerment. CMAvatar 3.0’s breakthrough in capturing quadruped animals and complex props is essentially a manifestation of CHINGMU’s brand philosophy of "capturing every frame of brilliance." It shatters the inertia that motion capture equals human-only capture, preserving the wild vitality of animals and the mechanical aesthetics of props in digital form. More importantly, its intelligent and efficient technology enables creative teams of all scales to effortlessly handle high-difficulty scenarios, significantly lowering the threshold for industry innovation.

When technology transcends mere imitation of humans and learns to understand all things, the ceiling of creativity is truly broken. We aspire to enable every industry and every form of creativity to find its own digital voice.
