Texture filtering algorithm for drawing of bilinearly filtered textures instead If ‘specialFlags’ is set to 2 then PTB will try to use its own high quality Use of GL_TEXTURE_2D textures isĬurrently not automatically compatible with use of specialFlags settings 2 or 4. OpenGL 3D graphics functions and for blurring. GL_TEXTURE_2D textures areĮspecially useful for animation of drifting gratings, for simple use with the Otherwise Psychtoolbox will try to pick the most optimal formatįor fast drawing and low memory consumption. Textures, then the texture is created as an OpenGL texture of type The width and height of the imageMatrix are powers of two (e.g., 64 x 64, 256 xĢ56, 512 x 512, …), or your graphics card supports so called non-power-of-two ![]() Theĭefault is 0 = Optimize for upright drawing. The texture for especially fast drawing at the specified rotation angle. The argument ‘optimizeForDrawAngle’ if provided, asks Psychtoolbox to optimize You need to enable Alpha-Blending via Screen(‘BlendFunction’,…) for the Range, so that they fit in with real HDR color range images. Uint8 image matrices will be remapped to a suitable subset of the HDR color HDR display window, then by default floating point textures will be created, and ‘imageMatrix’ matrices of double precision type, as does the optional The Screen(‘ColorRange’) command affects the range of expected input values in Alpha values typically range between zero (=fully transparent) and 255 Planes, RGB planes, or RGBA planes where A is alpha, the transparency of a The imageMatrix argument may consist of one monochrome plane (Luminance), LA In the OpenGL Psychtoolbox textures replace offscreen windows for fast drawing Index which may be passed to ‘DrawTexture’ to specify the texture.

Contribute work or money to the project.Some of its functionality is availableĪs part of Python toolkits like PsychoPy.įor commercial support and services visit Follow us on Twitter Getting started It makes it easy to synthesizeĪnd show accurately controlled visual and auditory stimuli and interact with the observer. GNU Octave functions for vision and neuroscience research. Believe me, you have my sympathy because these relatives are toxic.Psychophysics Toolbox Version 3 (PTB-3) is a free set of Matlab and However, because you have already done that, I don’t think it would enlighten them. Should you tell these family members how you feel? Ordinarily, I would say yes. It’s very important that you spend time with people - other family members or friends - who help you to feel BETTER about yourself rather than worse. Should I tell them how I feel or what? - DEVALUED IN THE SOUTHĭEAR DEVALUED: A family member (!) who would say something so cruel as what you have described is someone you should avoid contact with, if possible. When I say something to them about the way they make me feel, they tell me to be quiet and mind my own business. They are always saying I will never amount to anything. I was told from the beginning that I was a “mistake.” I am wondering, should I stay hurt with them for saying these things, or should I let it go? I have family members who say if I weren’t around, things would be a lot better. If it will make you feel more secure, install security cameras in your apartment, and if you catch him peering into your windows again, tell him you have him on camera and you will report him not only to building management but also the police.ĭEAR ABBY: I’m a middle-aged woman needing to know what to do. If he asks any more personal questions or comments again about your boyfriend’s absence, tell him your social life is none of his business. If he knocks on your door again, tell him you are busy and don’t like being disturbed and to stop doing it. Talk to your other neighbors and ask if he has a history of doing this with them. You can’t stop someone from walking his dog past your front door if that is where the exit is located. What should I do? - WARY IN WASHINGTONĭEAR WARY: The person you describe may be more lonely - or nosy - than dangerous. It’s also happening right in front of the building I live in, which makes me nervous. I want to confront him, but I’m not sure what to say. I haven’t answered because he makes me feel unsafe. ![]() I tried closing the blinds, but now he comes to my door and knocks. The couple of times he has seen me outside, he has asked me if I live “all alone” or comments that he “hasn’t seen my boyfriend around in a long time.” He peers into my window when he walks and lingers, despite my growling and snarling dog.
