RELATIONSHIPS ON ABILITY TO DRAW SHAPES AND SKETCHES WITH STUDENTS EXPRESSIVE DRAWING

This study aims to prove whether there is a significant relationship, the amount of contribution (contribution), and to see the size of the relationship between the ability to draw shapes and sketches with the ability to draw expressive in class X SMA Bangun Insan Mandiri Medan. The method used in this research is correlational research, which is to see the relationship between the two independent variables and the dependent variable. The population in this study were students of class X SMA Bina Insam Mandiri Medan for the 2019/2020 academic year, totaling 32 students. Based on the results of research and discussion, it can be concluded that there is a relationship between the ability to draw shapes and draw sketches simultaneously on the expressive drawing ability of class X students of SMA Bangun Insan Mandiri Medan. Partially there is a relationship between the ability to draw shapes and the expressive drawing ability of class X SMA Bangun Insan Mandiri Medan, Partially there is a relationship between drawing a sketch and the expressive drawing ability of grade X students of SMA Bangun Insan Mandiri Medan.ABSTRAK Penelitian ini bertujuan untuk membuktikan ada tidaknya hubungan yang signifikan, besarnya kontribusi, dan untuk melihat besar kecilnya hubungan antara kemampuan menggambar bentuk dan sketsa dengan kemampuan menggambar ekspresif pada siswa kelas X SMA Bangun Insan Mandiri Medan.

Eye placement bias is remarkably robust

When drawing faces, people show a systematic bias of placing the eyes higher up the head than they are placed in reality. The current study investigated the development of this phenomenon while removing the potential confound of drawing ability. Participants (N = 124) in three age groups (3-5yo, 10-11yo, and adults) reconstructed two foam faces, one from observation and one from memory. The high eye placement bias was remarkably robust with mean eye placement in every condition significantly higher than the original faces. The same bias was not shown for mouth placement. Eye placement was highest for the youngest participants and for the memory conditions. The results suggest that an eye placement bias is not caused by the motor skill demands required for drawing and lend evidence to the suggestion that an eye placement bias is caused by perceptual and decision-making processes.

ALGORITMA NON-PHOTOREALISTIC RENDERING UNTUK KARTUN MENGGUNAKAN K-MEANS DAN CANNY

Cartoons are one type of illustration usually in a non-realistic or semi-realistic style. To make a cartoon drawing manually requires good drawing ability. So, not everyone can make cartoons. This research proposes a non-photorealistic rendering algorithm to create cartoon drawings automatically. The algorithm consists of four phases. First, create an image abstraction using bilateral filtering. Second, using kmeans clustering for abstract image quantization. Third, get the contour lines of the drawing using the canny algorithm. Fourth, contour lines and quantized images are combined. The results show that this algorithm can produce good visualization of cartoon images.
