With the rapid development of computer graphics , image processing technology and three-dimensional modeling techniques, the approach of the Art Design extends to the computer-aided design from the original hand-drawn. Since three-dimensional computer graphics software effects processing and display of 3D modeling software, strengthens the beauty and expressions of Graphic Arts, In the individual performance, ordered, three-dimensional effects and innovative design, etc. all have different design performance and function. More importantly, with the help of computer, an advanced tool, so many design ideas and effects using traditional performance art design methods are difficult to be realized. What is more, Image and behaving more realistic visual communication has greatly improved the performance of the force.

Abstract Among cartographic works, three-dimensional panoramas should be marked out as a special kind of map, which are characterised by visual modes of representing objects in space. The main principles of the creation of both hand-painted and automated maps vector and raster graphics software (Corel Draw and Adobe Photoshop) are considered in the paper. The use of modern information technologies has several advantages over traditional mapping.

Stereo pairs of electron microscope images provide valuable visual impressions of the three-dimensional nature of specimens, including biological objects. Beyond this one seeks quantitatively accurate models and measurements of the three dimensional positions and sizes of structures in the specimen. In our laboratory, we have sought to combine high resolution video cameras with high performance computer graphics systems to improve both the ease of building 3D reconstructions and the accuracy of 3D measurements, by using multiple tilt images of the same specimen tilted over a wider range of angles than can be viewed stereoscopically. Ultimately we also wish to automate the reconstruction and measurement process, and have initiated work in that direction.Figure 1 is a stereo pair of 400 kV images from a 1 micrometer thick transverse section of frog skeletal muscle stained with the Golgi stain. This stain selectively increases the density of the transverse tubular network in these muscle cells, and it is this network that we reconstruct in this example.

The paper presents the opportunities to apply computer graphics in an object floodlighting design process and in an analysis of object illumination. The course of object floodlighting design has been defined based on a virtual three-dimensional geometric model. The problems related to carrying out the analysis of lighting, calculating the average illuminance, luminance levels and determining the illuminated object surface area are also described. These parameters are directly tied with the calculations of the Floodlighting Utilisation Factor, and therefore, with the energy efficiency of the design as well as the aspects of light pollution of the natural environment. The paper shows how high an impact of the geometric model of the object has on the accuracy of photometric calculations. Very often the model contains the components that should not be taken into account in the photometric calculations. The research on what influence the purity of the geometric mesh of the illuminated object has on the obtained results is presented. It shows that the errors can be significant, but it is possible to optimise the 3D object model appropriately in order to receive the precise results. For the example object presented in this paper, removing the planes that do not constitute its external surface has caused a two-fold increase in the average illuminance and average luminance. This is dangerous because a designer who wants to achieve a specific average luminance level in their design without optimizing the model will obtain the luminance values that will actually be much higher.
