@niemand 这个形状真的好像动漫里的啊
我做不出来这样的
@niemand 诶?好久不见
就是这篇论文:http://www.cemyuksel.com/research/interpolating_splines/
关于 C2 连续的样条插值。思路特别简单,我觉得最神奇的就是仅仅 Eq. 2 一项就可以满足 C2 了,这是怎么想到的…整个论文最关键的也只有等式一等式二和图二图三而已,特别好懂,其他的基本都是在阐述性质。如果基本函数选择 Bezier 曲线的话 convex hull 这样的良好性质也可以保留…
好久没读这种不花里胡哨的论文了
本来在想要不要做论文导读的,但是我感觉 Cem Yuksel 他自己就讲得很好了,他 YouTube 上还有一系列 Computer Graphics 的课也都讲得特别好
social anxiety disorder 一章节选,很长,讲了社交恐惧症的可能原因、治疗方法。
@kmethne 漏了一节,是说除了克服恐惧以外还应该学习和提升社交技巧,但说的都是在 therapist 的指导下进行的。如果你情况很严重,也许应该去找一个 cognitive 方向的 therapist。只是社交恐惧而没有社交恐惧“症”的话,也许可以自行治疗?

*What Causes Social Anxiety Disorder?*
The leading explanation for social anxiety disorder has been proposed by cognitive-behavioral theorists (Thurston et al., 2017; Heimberg et al, 2010). The explanation features an interplay of both cognitive and behavioral factors. As you read in Chapter 3, cognitive-behavioral theorists start with the contention that people with this disorder hold a group of dysfunctional beliefs and expectations regarding the social realm. These can include:
- Holding unrealistically high social standards and so believing that they must perform perfectly in social situations
- Believing they are unattractive social beings.
- Believing they are socially unskilled and inadequate.
- Believing they are always in danger of behaving incompetently in social situations.
- Believing that inept behaviors in social situations will inevitably lead to terrible consequences.
- Believing they have no control over feelings of anxiety that emerge in social situations.
Cognitive-behavioral theorists hold that, because of these beliefs, people with social anxiety disorder keep anticipating that social disasters will occur, overestimate how poorly things go in their social interactions, and dread most
social situations (Gavric et al., 2017). Moreover, they learn to perform “avoidance” and “safety” behaviors to help prevent or reduce such disasters.
*Treatments for Social Anxiety Disorder*
Only in recent decades have clinicians been able to treat social anxiety disorder successfully. Their success is due in part to the growing recognition that the disorder has two distinct features that may feed upon each other: (1) sufferers have overwhelming social fears, and (2) they often lack skill at starting conversations, communicating their needs, or meeting the needs of others. Armed with this insight, clinicians now treat social anxiety disorder by trying to reduce social fears, by providing training in social skills, or both.
*How Can Social Fears Be Reduced?*
Medication often helps alleviate social fears (Curtiss et al., 2017). Such fears are reduced to some degree in 55 percent of patients who take either benzodiazepines or antidepressant drugs, compared to 24 percent of similar patients who take placebo drugs (Stein, 2016). It appears that these medications bring about relief by improving functioning in the brain’s fear circuit, which tends to be
hyperactive for people with social anxiety disorder, just as it is in cases of generalized anxiety disorder (Brühl et al., 2014).
At the same time, cognitive-behavioral therapy has proved to be at least as effective as medication at reducing social fears, and people helped by this approach seem less likely to relapse than those treated with medications alone (Gregory & Peters, 2017; Thurston et al., 2017; Heimberg & Magee, 2014). This finding suggests to some clinicians that this form of therapy should always be featured in the treatment of social fears, either alone or in combination with medication.
To undo the cycle of problematic social beliefs and behaviors described earlier, cognitive-behavioral therapists combine both behavioral and cognitive techniques. On the behavioral side, they conduct exposure therapy, the intervention so effective with phobias. The therapists encourage clients to expose themselves to their dreaded social situations and to remain in these situations as their fears subside. Usually the exposure is gradual, and it often includes homework assignments. On the cognitive side, the clinicians and clients have systematic therapy discussions in which the clients are guided to re-examine and challenge their maladaptive beliefs and expectations, given the less-than-dire outcomes of their social exposures.
@kmethne 我听过的说法是,社恐普遍把社交这件事情想象得太恐怖了,或者是过于苛求自己的表现。其实如果你真的去社交几次的话,会发现其实也不会发生什么,也没有人要求你表现完美。
是在 Abnormal Psychology 里读到的。
如果真的去社交了发现确实恐确实不舒服的话,也许是接触的人群不对
@Schneevongestern 你到底是做什么的
@ChuckL 小心我拱你
