| 17 | This short paper is well written en clearly structured. The authors give a nice
|
|---|
| 18 | overview of the related work and other similar systems.
|
|---|
| 19 |
|
|---|
| 20 | However, it is not really a research paper as it does not contain a description as
|
|---|
| 21 | to how this system, or the extension, is different from the others in the field. A
|
|---|
| 22 | question which arises is how the authors cope with any problems that others might
|
|---|
| 23 | have.
|
|---|
| 24 |
|
|---|
| 25 | A nice extension would be to more clearly highlight the differences with others.

| 35 | The paper explains how animation can be provided in a game engine.
|
|---|
| 36 |
|
|---|
| 37 | Animation is still a difficult aspect on game design, as it requires a high amount
|
|---|
| 38 | of user input. I therefore find the subject of the paper interesting and relevant,
|
|---|
| 39 | but the design and engineering aspects of the paper are not always clear. It often
|
|---|
| 40 | reads as a description of functionalities that is realized by interfacing existing
|
|---|
| 41 | software libraries.
|
|---|
| 42 |
|
|---|
| 43 | Should this paper be accepted, I would therefore recommend to shorten the content on
|
|---|
| 44 | the first two pages and to focus more on the example of human walking. The paper
|
|---|
| 45 | already gives some hints to the design aspects, but these should be elaborated on in
|
|---|
| 46 | more detail.

| 56 | The paper presents recent results gained by the addition of new components dedicated
|
|---|
| 57 | to the physical simulation of virtual worlds to the Crystal Space Engine. These are
|
|---|
| 58 | a skeletal animated mesh, an animation blending tree, and several new animation
|
|---|
| 59 | nodes.
|
|---|
| 60 |
|
|---|
| 61 | In the introduction section the authors present several requirements for realizing
|
|---|
| 62 | realistic motions in virtual scenes and note that even simple actions, such as
|
|---|
| 63 | walking depend on several parameters, such as the gender, the body size and weight.
|
|---|
| 64 | Further on, grabbing intelligence, complex movements for collision avoidance, the
|
|---|
| 65 | consideration of human skin bends as well as the consideration of face muscles is
|
|---|
| 66 | stated as important.
|
|---|
| 67 |
|
|---|
| 68 | In the following sections these requirements were not explicitly addressed and thus
|
|---|
| 69 | it remains unclear how the described plugins as well as the blending trees are
|
|---|
| 70 | utilized to implement for instance the grabbing intelligence.
|
|---|
| 71 |
|
|---|
| 72 | The related work section argues mainly by citing web references to software products
|
|---|
| 73 | but misses a consideration of relevant scientific work in the area of animation in
|
|---|
| 74 | virtual worlds. When reading the discussion about already existing software it
|
|---|
| 75 | remains unclear, on which related work the authors work is based on as well as it
|
|---|
| 76 | misses to state the reasons for the choice. A detailed discussion of related work
|
|---|
| 77 | based on the initially presented requirements is missing.
|
|---|
| 78 |
|
|---|
| 79 | The following sections 'Physical Simulation' as well as 'Skeletal Animation' are
|
|---|
| 80 | unstructured and miss some kind of a connection to the previous section and it is
|
|---|
| 81 | hard to differentiate the description of the already existing parts of the Crystal
|
|---|
| 82 | Space engine and the authors' additions.
|
|---|
| 83 |
|
|---|
| 84 | Suggestions:
|
|---|
| 85 |
|
|---|
| 86 | Characterize the related work based on the requirements, otherwise it remains
|
|---|
| 87 | unclear which aspects are completely new or if the main outcome is the combination
|
|---|
| 88 | of all requirements.
|
|---|
| 89 |
|
|---|
| 90 | To the end of the introduction there should be a paragraph describing the upcoming
|
|---|
| 91 | structure of the paper. There it should be added as well, which sections describe
|
|---|
| 92 | basic concepts and existing features of CS (sections: Concepts of physical 'pysical simulation')
|
|---|
| 93 |
|
|---|
| 94 | For the state of the art section it would be especially interesting to
|
|---|
| 95 | differentiate: which additions 1) are completely new or implement a more efficient
|
|---|
| 96 | algorithm, 2) are already existing in commercial products but have not been made
|
|---|
| 97 | available to the public (e.g. by open source or papers describing the algorithms).
|
|---|
| 98 | Further on relevant scientific work needs to be identified and discussed. References
|
|---|
| 99 | need to quote the date they have been accessed the last time.
