The paper studies the history of the development of digital technologies according to the growing possibilities of computer graphics. We consider the influence of computer technologies on graphics in retrospect starting from the middle of the last century to the present day: from drawing on an oscilloscope screen using light pens to creating complete interfaces; from the use of the first computers to the technology of generating three-dimensional images in real time. The study pays attention to such types of image representation as vector, raster, fractal and three-dimensional graphics and highlights the differences between them as well as the ways, methods and areas of application. We demonstrate how the progress in the field of technical means influences traditional forms of art and on the emergence of completely new art forms: pixel art, low poly art etc. The paper also dwells on generative art, three-dimensional sculpture, net-graphics, video art and other areas.

This chapter introduces the Isoluminance Contour Model, which not only provides a quick and easy method for generating images, but also dramatically reduces the amount of work required by traditional computer graphics methods. It starts with the history of the model from its conception in 1981: it was used to generate flat-shaded greyscale, simple, primitive objects such as cubes, cylinders, cones, and spheres, by generating full-color smooth-shaded images for animated sequences. The model compares the degree of realism and the speed of production it generates with that achieved by using smooth shading and ray-tracing methods. It ultimately describes how the amount of data used by the Isoluminance Contour Model can be adapted dynamically to suit the screen size of the primitive object being generated, making real-time 4-dimensional animated visualization feasible on a Pentium 400 (or equivalent) or faster PC.

SIMdisaster is a simulation software conceived to respond to the training needs of health operators managing aid in maxi-emergencies, since the reproduction of such events for didactic purposes proves to be both complex and costly. SimDisaster reconstructs the scenario of a catastrophe using photos and films manipulated using computer graphics and integrated with three-dimensional objects generated by the computer. An interactive interface makes it possible to assess the scenario and hence take decisions about the logistics of aid operations, the choice of auto-protection techniques, triage intervention and maintenance of the principal vital functions. The scenario then evolves in real time depending on the choices made by the user.

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 Paris avant-garde milieu from which both Cirque Calder/Calder's Circus and Painlevé’s early films emerged was a cultural intersection of art and the twentieth-century life sciences. In turning to the style of current scientific journals, the Paris surrealists can be understood as engaging the (life) sciences not simply as a provider of normative categories of materiality to be dismissed, but as a companion in apprehending the “reality” of a world beneath the surface just as real as the one visible to the naked eye. I will focus in this essay on two modernist practices in new media in the context of the history of the life sciences: Jean Painlevé’s (1902–1989) science films and Alexander Calder's (1898–1976) work in three-dimensional moving art and performance—the Circus. In analyzing Painlevé’s work, I discuss it as exemplary of a moment when life sciences and avant-garde technical methods and philosophies created each other rather than being classified as separate categories of epistemological work. In moving from Painlevé’s films to Alexander Calder's Circus, Painlevé’s cinematography remains at the forefront; I use his film of one of Calder's performances of the Circus, a collaboration the men had taken two decades to complete. Painlevé’s depiction allows us to see the elements of Calder's work that mark it as akin to Painlevé’s own interest in a modern experimental organicism as central to the so-called machine-age. Calder's work can be understood as similarly developing an avant-garde practice along the line between the bestiary of the natural historian and the bestiary of the modern life scientist.
